# 3. Installation
## 3.1. Install via npm or yarn

**`$ npm i vue-bootstrap4-table --save`**

**`$ yarn add vue-bootstrap4-table`**

Currently this package will install only the vue-bootstrap4-table component, not their dependencies. So make sure to install the following dependencies.

### 3.1.1. Dependencies

-   bootstrap 4 (js and css) You should include bootstrap before vue-bootstrap4-table plugin.


We are using **`lodash`** internally, so you don't need to install separately for this plugin.

## 3.2. Install via CDN
```html
<link  rel="stylesheet"  href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"  crossorigin="anonymous">

...
<script  src="https://code.jquery.com/jquery-3.2.1.slim.min.js"  crossorigin="anonymous"></script>

<script  src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js"  crossorigin="anonymous"></script>

<script  src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/js/bootstrap.min.js"  crossorigin="anonymous"></script>

...

<script  src="https://unpkg.com/vue-bootstrap4-table@1.1.10/dist/vue-bootstrap4-table.min.js"  crossorigin="anonymous"></script>
```
**Note:** If you've included bootstrap & jQuery packages already in your project, then include only **vue-bootstrap4-table.min.js** script.

# 4. Basic Usage
It is easy to include vue-bootstrap4-table as a component in your application.

Import VueBootstrap4Table component in any of your vue component and start using it right away.

**Note:** If you included the library via CDN, then you don't need to import, you can use **`vue-bootstrap4-table`**  component right away.

**`rows`** and **`columns`** props should be passed down to **`vue-bootstrap4-table`** component to work with the table.

```vue
<template>
    <div id="app">
        <vue-bootstrap4-table :rows="rows" :columns="columns" :config="config">
        </vue-bootstrap4-table>
    </div>
</template>

<script>
import VueBootstrap4Table from 'vue-bootstrap4-table'

export default {
    name: 'App',
    data: function() {
        return {
            rows: [{
                    "id": 1,
                    "name": {
                        "first_name": "Vladimir",
                        "last_name": "Nitzsche"

                }],
            columns: [{

    },
    components: {
        VueBootstrap4Table
    }
}
</script>
```
# 5. Columns
## 5.1. Basic structure
For example, your "columns" object might look like this,

```javascript
columns: [{
        label: "id",
        name: "id",
        filter: {
            type: "simple",
            placeholder: "Enter id"
        },
        sort: true,
        uniqueId: true
    },
    {
        label: "First Name",
        name: "name.first_name", // access nested objects properties with "."
        filter: {
            type: "simple",
            placeholder: "Enter first name",
            case_sensitive: true, // "false" by default
        },
        sort: true, // "false" by default
        initial_sort: true, // "false" by default
        initial_sort_order: "desc" // "asc" by default
    },
    {
        label: "Email",
        name: "email",
        sort: true,
        row_text_alignment:  "text-left",
        column_text_alignment:  "text-left",
        row_classes:  "my-row-class1 my-row-class2",
        column_classes:  "my-column-class1 my-column-class2"
    },
    {
        label: "Country",
        name: "address.country", // access nested objects properties with "."
        filter: {
            type: "simple",
            placeholder: "Enter country"
        },
        visibility: false
    }]
```

## 5.2. Attributes details
|Attributes|Description|Type|Default|
|--|--|--|--|
|label | Name for the column header | String| " " |
|name | Name of the attribute that you would like to show from **`"rows"`** object. You can access nested objects properties with "." | String| " " |
|slot_name | Overrides default slot name assignment. For more details refer "Rows" section | String| " " |
|uniqueId | You can teach table which column has unique values. It helps table to do faster operations and it is really useful in "server_mode". | Boolean| false |
|visibility | Show/Hide specific column. | Boolean| true |
|filter | Configuration for the column filter. If you don't want to have filtering for specific columns, then just don't mention it :-) | Object| Empty |

| column_classes | You can specify your custom classes for each column header. You can add multiple classes with a space delimiter.This classes will be added to **`<th>`** element. |  String|" "  |

## 5.3. Column slot

At some point, you might want to override or format the values in the column header. **`vue-bootstrap4-table`** allow you to achieve that with the help of vue slotting.
### 5.3.1. Example

```vue
...
<vue-bootstrap4-table :rows="rows" :columns="columns" :config="config">
    <template slot="column_email" slot-scope="props">
        <i>
            {{props.column.label}}
        </i>
    </template>
    <template slot="column_name_first_name" slot-scope="props">
        <b>
            {{props.column.label}}
        </b>
    </template>
</vue-bootstrap4-table>
...
<script>
...
columns: [{
            label: "First Name",
            name: "name.first_name", // access nested objects properties with "."
            sort: false,
        },
        {
            label: "Email",
            name: "email",
            sort: true,
        }],
...
</script>
```
Column slot name will be combination of **`column_`** keyword with the **`name`** which you provided in the columns configuration. In the above example, **`slot="column_email"`** represents the "email" column header in the table.

### 5.3.2. Note
You might have some columns with nested objects names. In that case, the slot name will be **`column_`** keyword + column **`name`** and dots(.) in the column **`name`** will be replaced by underscore(_).

You can see the above example, slot name for **`name.first_name`** column is **`column_name_first_name`**.

### 5.3.3. props
From **`slot-scope="props"`** you can access the following attributes.

|Attributes  | Description |
|--|--|
| props.column | Current column config object |
# 6. Rows
You bind your list of items as array of objects to **`rows`** props to **`vue-bootstrap4-table`** component, then voilà.. you can start work with the table.
## 6.1. Basic structure
```javascript
rows: [{
        "id": 1,
        "name": {
            "first_name": "Vladimir",
            "last_name": "Nitzsche"
        },
        "address": {
            "country": "Mayotte"
        },
        "email": "franecki.anastasia@gmail.com",
    },
    {
        "id": 2,
        "name": {
            "first_name": "Irwin",
            "last_name": "Bayer"
        },
        "age": 23,
        "address": {
            "country": "Guernsey"
        },
        "email": "rlittle@macejkovic.biz",
    },
    {
        "id": 3,
        "name": {
            "first_name": "Don",
            "last_name": "Herman"
        },
        "address": {
            "country": "Papua New Guinea"
        },
        "email": "delia.becker@cormier.com",
    }]
```
## 6.2. Row Slot
At some point, you might want to override or format the values in the row cells. **`vue-bootstrap4-table`** allow you to achieve that with the help of vue slotting.
### 6.2.1. Example
```vue
...
<vue-bootstrap4-table :rows="rows" :columns="columns" :config="config">
    <template slot="email" slot-scope="props">
        <i>
            {{props.cell_value}}
        </i>
    </template>
    <template slot="name_first_name" slot-scope="props">
        <b>
            {{props.cell_value}}
        </b>
    </template>
    <template slot="lastname" slot-scope="props">
        <b>
            {{props.cell_value}}
        </b>
    </template>
</vue-bootstrap4-table>
...
<script>
...
columns: [{
            label: "First Name",
            name: "name.first_name" // access nested objects properties with "."
        },
        {
            label: "Last Name",
            name: "name.last_name", // access nested objects properties with "."
            slot_name: "lastname" // optional, if you don't provide slot name
                                  //then default slot name will be name_last_name
        },
        {
            label: "Email",
            name: "email"
        }],
...
</script>
```
Slot name will be same as the name which you provided in the columns configuration. In the above example, **`slot="email"`** represents the "email" column in the table.
### 6.2.2. Note
You might have some columns getting the values from nested objects from **`rows`**. In that case, the slot name will be column **`name`** and dots(.) in the column **`name`** will be replaced by underscore(_).

You can see the above example, slot name for **`name.first_name`** column is **`name_first_name`**.

If you don't like this default "slot name" assignment, then you can set names to row slots as shown in the above example.

### 6.2.3. props
From **`slot-scope="props"`** you can access the following attributes.

                        btn_text: "Download",
                        event_name: "on-download",
                        class: "btn btn-primary my-custom-class",
                        event_payload: {
                            msg: "my custom msg"
                        }
                    }
                ],
                config: {
                    ...
                }
            }
        },
        methods: {
            onDownload(payload) {
                console.log(payload);
            }
        },
        components: {
            VueBootstrap4Table
        }
    }
</script>
```

Each action object should contain the below attributes.

## 12.2. Attributes details

| Attributes | Description | type | Default |
|--|--|--|--|
| btn_name | Display name for the button |String  |  " "|
| event_name |  Name of the event that you want to listen back (Mandatory)| String | undefined |
| class | Class which you want to override default button classes | String | " " |
| event_payload | Payload you want to send with the event | Any | undefined |

# 13. Custom classes

You can pass your classes for the table, row, cell, etc.. via **`classes`**  prop. And interesting thing is you can pass a validator function to apply custom classes conditionally.

## 13.1. Example
```vue
<template>
    <div id="app">
        <vue-bootstrap4-table :classes="classes"
                              :rows="rows"
                              :columns="columns">
        </vue-bootstrap4-table>
    </div>
</template>

<script>
    import VueBootstrap4Table from 'vue-bootstrap4-table'
    export default {
        name: 'App',
        data: function() {
            return {
                rows: [
                    ...
                ],
                columns: [
                    ...
                ],
                classes: {
                    tableWrapper: "outer-table-div-class wrapper-class-two",
                    table : {
                        "table-striped my-class" : true,
                        "table-bordered my-class-two" : function(rows) {
                            return true
                        }
                    },
                    row : {
                        "my-row my-row2" : true,
                        "function-class" : function(row) {
                            return row.id == 1
                        }
                    },
                    cell : {
                        "my-cell my-cell2" : true,
                        "text-danger" : function(row,column,cellValue) {
                            return column.name == "salary" && row.salary > 2500
                        }
                    }
                }
            }
        },
        components: {
            VueBootstrap4Table
        }
    }
</script>
```
Currently you can add custom classes to **`<div>, <table>, <tr> and <td>`** elements for table outer div element, table, row, and cell properties respectively.

You can either pass the custom classes directly or pass a function with your condition check to decide whether to apply to class or not.

For example, in the above example, look at the property **`cell`**. There we are applying classes **"my-cell my-cell2"** directly to **`<td>`** element and **"text-danger"** class only to the "salary" column & also the salary value should be above 2500.

# 14. vbt-classes
By default, vue-bootstrap-table add classes to table elements which allows users to override the default styles.
## 14.1. vbt-row-selected
If a row is being selected with checkbox or row, then the selected row <tr> element will have "vbt-row-selected" class attached to it.

```html
<tr class="vbt-row-selected">
    ...
</tr>
```
## 14.2. vbt-table-wrapper
This class is being applied to outer <div> element of <table> element.

```html
<div class="vbt-table-wrapper">
    <table>
        ...
    </table>
</div>
```

# 15. Config
You can optionally pass config as a prop to **`vue-bootstrap4-table`** component to override the table configuration defaults.

## 15.1. Example
```vue
<template>
    <div id="app">
        <vue-bootstrap4-table :rows="rows" :columns="columns" :config="config">
        </vue-bootstrap4-table>
    </div>
</template>

<script>
    import VueBootstrap4Table from 'vue-bootstrap4-table'

    export default {
        name: 'App',
        data: function() {
            return {
                rows: [
                ...
                ],
                columns: [
                ...
                ],
                config: {
                    card_mode:  true,
                    selected_rows_info:  false,
                    pagination: true,
                    pagination_info: true,
                    num_of_visibile_pagination_buttons: 7,
                    per_page: 5,
                    checkbox_rows: true,
                    highlight_row_hover: true,
                    rows_selectable: true,
                    multi_column_sort: true,
                    highlight_row_hover_color:"grey",
                    card_title: "Vue Bootsrap 4 advanced table",
                    global_search:  {
	                    placeholder:  "Enter custom Search text",
	                    visibility:  true,
	                    case_sensitive:  false
	                },
	                per_page_options:  [5,  10,  20,  30],
	                show_refresh_button:  true,
	                show_reset_button:  true,
	                server_mode:  true,
                    preservePageOnDataChange: true
                }
            }
        },
        components: {
            VueBootstrap4Table
        }
    }
</script>
```

> If you don't provide an attribute in the config, then default value will be assigned to that attribute.

## 15.2. Attributes details

|Attributes  | Description | type| Default |
|--|--|--|--|
| card_mode | You can choose between table surrounded with card layout and plain default table alone.| Boolean | true |
| pagination | Enable/Disable pagination in the table |Boolean |  true|
| pagination_info | Enable/Disable pagination info in the table | Boolean|  true|
|selected_rows_info |Enable/Disable number of rows selected info in the table | Boolean | false |
| num_of_visibile_pagination_buttons | Limit the number of visible pagination buttons in the pagination bar |Number | 5 |
| per_page | Number of rows to display per page |Number | 10  |
| checkbox_rows | Enable/Disable checkbox in each rows |Boolean | false |

| card_title | Sets the table title in the card header | String| "" (empty string) |
|  global_search.placeholder | Placeholder is **`hint`** text for search text box  | String  |  "Enter search text" |
| global_search.visibility  |  Show/Hide global search text input |  Boolean |  true |
|global_search.case_sensitive   | Enable/Disable case sensitive searching.  | Boolean  |  false |

| show_refresh_button  |  Show/Hide Refresh button | Boolean  | true  |
| show_reset_button  |  Show/Hide Refresh button. Resets all query (sort, filter, global search) currently applied in the table. |Boolean   | true  |
| server_mode  |  Enable/Disable server side processing (Sorting, Filtering, Global search & pagination) |Boolean   | false  |
| preservePageOnDataChange  |  Enable/Disable preserving current index of the page on data change. For example, if this option is set to true, consider that you are in page **4** and performed some actions like sorting or filtering, then now table gets a new data and still the pagination will be in page **4**. If this config is set to false (default), for any data change current page in the pagination will be shifted to page **1**. |Boolean   | false  |

# 16. Server mode

In server mode, client side filtering, sorting, global search and pagination will be disabled. Instead your server will do all this and returns only the processed response. New response will update the rows in the table.

## 16.1. Example

```vue
<template>
    <div id="app">
        <vue-bootstrap4-table :rows="rows"
                              :columns="columns"
                              :config="config"
                              @on-change-query="onChangeQuery"
                              :totalRows="total_rows">
        </vue-bootstrap4-table>
    </div>
</template>

<script>
    import VueBootstrap4Table from 'vue-bootstrap4-table'
    export default {
        name: 'App',
        data: function() {
            return {
                rows: [],
                columns: [
                ...
                ],
                config: {
                    ...
                    server_mode: true // by default false
                    ...
                },
                queryParams: {
                    sort: [],
                    filters: [],
                    global_search: "",
                    per_page: 10,
                    page: 1,
                },
                total_rows: 0,
            }
        },
        methods: {
            onChangeQuery(queryParams) {
                this.queryParams = queryParams;
                this.fetchData();
            },
            fetchData() {
                let self = this;
                axios.get('http://example.com/search', {
                        params: {
                            "queryParams": this.queryParams,
                            "page": this.queryParams.page
                        }
                    })
                    .then(function(response) {
                        self.rows = response.data.data;
                        self.total_rows = response.data.total;
                    })
                    .catch(function(error) {
                        console.log(error);
                    });
            }

        },
        components: {
            VueBootstrap4Table
        },
        mounted() {
            this.fetchData();
        },
    }
</script>

<style>

</style>
```

### 16.1.1. Step 1

In your application you should have the below information in **`data.`**

```javascript
queryParams: {
    sort: [],
    filters: [],
    global_search: "",
    per_page: 10,
    page: 1,
},
total_rows: 0,
```

### 16.1.2. Step 2

If you want to work with pagination, then don't forget to set **`total_rows`** as prop to **`totalRows`**.

Then listen for the event **`on-change-query`**.

```vue
<vue-bootstrap4-table :rows="rows"
        :columns="columns"
        :config="config"
        @on-change-query="onChangeQuery"
        :totalRows="total_rows">
</vue-bootstrap4-table>
```

### 16.1.3. Step 3

Wherever there is a change in table query params, you will get your new query params in your **`onChangeQuery`** function. With the new values update your **`queryParams`** and fetch new data from server.

```javascript
onChangeQuery(queryParams) {
    this.queryParams = queryParams;
    this.fetchData();
},
```

### 16.1.4. Step 4

I assume you are using **`axios`** library for handling ajax requests.

Once you have the new updated result, update **rows** with new data and also update **`total_rows`** with the total number of records.

```javascript
fetchData() {
    let self = this;
    axios.get('http://example.com/search', {
            params: {
                "queryParams": this.queryParams,
                "page": this.queryParams.page
            }
        })
        .then(function(response) {
            self.rows = response.data.data;
            self.total_rows = response.data.total;
        })
        .catch(function(error) {
            console.log(error);
        });
}
```
### 16.1.5. Note
To get best performance, it is recommended to mention in column config that which column have unique values. You can refer the below example.
```javascript
columns: [
    ...
    {
        label: "id",
        name: "id",
        filter: {
            type: "simple",
            placeholder: "Enter id"
        },
        sort: true,
        uniqueId: true // like this
    }
    ...
]
```
