## Custom borders

To enable the custom borders feature, set the `customBorders` option. It could be set as `true` or initialized as an array with predefined setup.

To initialize Handsontable with predefined custom borders, provide cells coordinates and border styles in form of an array:

- with row/col pairs: `{ row: 2, col: 2, left: { /*...*/ } }`
- or with range details: `{ range:{ from:{ row: 1, col: 1 }, to:{ row: 3, col: 4 } }, left: { /*...*/ } }`

See full example below.
