Steps to reproduce the problem:
Have a grid with:
When running the code that create the grid, the initial state looks like this:
Current behavior:
The header columns are filling the width of the grid (each bigger than the specified 100), but the rows columns cells have the specified width of 100, causing a misalignment.
However, changing the width of a column with the resize handle fixes all the widths (header + rows).
Same thing for adding/removing a column from the menu.
See the attached video for an example.
If in the initial state there are more shown columns so they can fill the grid width (and have the horizontal scrollbar), the issue is not present.
Expected behavior:
Rows columns should always match the width of the header.
