Angular Data Grid Column Sizing

Column sizing

Add drag-to-resize handles to Angular Data Grid header cells, with live or on-release width updates and per-column opt-out.

On this page

Let users widen a column to read long values or shrink one they don’t care about. columnSizing adds a drag handle to every resizable header cell; widths persist in the grid’s state and can be committed live or on release.

Column resizing

Set columnSizing to add a drag handle to the right edge of every header cell. Widths follow the pointer live ([columnSizing]="{ mode: 'onEnd' }" commits them on release instead), the grid scrolls horizontally once the columns outgrow the viewport, and column.width seeds the starting width. Opt a column out with resizable: false — here the # column stays fixed.

Options

Option	Type	Default	Description
`columnSizing`	`boolean \| { mode?: 'onChange' \| 'onEnd' }`	`false`	Enables resize handles. `mode` controls whether widths update while dragging (`'onChange'`, the default) or on release (`'onEnd'`).
`resizable` (column)	`boolean`	`true`	Set `false` to drop the resize handle for a column.
`width` (column)	`number`	—	Seeds the starting width in pixels, e.g. `200`.

Resizing emits the sizingChange output with the grid’s { columnSizing } state.
