Table: Expose column resize handlers to support column resizing

Package

v4.x

Description

The Table component forwards TanStack Table column options such as enableResizing, but there is currently no way to actually resize columns.

According to the TanStack Table documentation, enabling column resizing also requires wiring header.getResizeHandler() (or an equivalent API) to a resize handle in the UI.

At the moment, the Table component doesn't expose any way to access the resize handler or render a resize handle, so setting enableResizing: true has no visible effect.

Expected behavior

It should be possible to use TanStack's built-in column resizing through the Nuxt UI Table component, either by:

• Exposing header.getResizeHandler()
• Providing a resize handle in the default header implementation

Current behavior

enableResizing: true is accepted in the column definition, but columns cannot actually be resized because the required resize handler isn't accessible.

Additional context

TanStack Table already provides column resizing support:
https://tanstack.com/table/latest/docs/guide/column-sizing

The missing part is exposing the resize handler in the Nuxt UI Table component.

Start in the Nuxt UI Table component implementation and compare its header rendering and exposed APIs with TanStack Table's column-sizing documentation. Determine whether the handler should be exposed or rendered as a default resize handle, then verify that enabling column resizing allows columns to be resized through the component.
