Is your feature request related to a problem? Please describe.
Columns can only be resized by drag on the edges, but this is not an accessible method and is especially difficult on touch screens.

It can also be difficult to see where the click/drag target exactly is. MUI’s Data Grid is a good example of explicitly showing the drag target: https://mui.com/components/data-grid/columns/#resizing

Describe the solution you'd like
In the column menu, there should be an option to resize that opens a modal to set the column width, maybe with a preview.
