Inline editing checkbox column size inconsistency

[Deanobeano2]

Hi

I'm preparing a grid, in a view with several grids, for bulk editing and have noticed an inconsistency with the checkbox column sizes as attached.

If I change the Description field from the Custom width to Default width it does shrink significantly but still varies in size from the 1st grid's checkbox column.

Am I missing something like a setting somewhere, or can the checkbox column width be fixed somehow rather than being a "dynamic" width?
