## Horizontal & vertical alignment

To initialize Handsontable with predefined horizontal and vertical alignment, provide className cells details in form of a grid, `columns` or `cell` setting (see code sample below).

Available classNames:

- horizontal: `htLeft`, `htCenter`, `htRight`, `htJustify`,
- vertical: `htTop`, `htMiddle`, `htBottom`.

Alignment changes can be tracked using `afterSetCellMeta` hook callback.
