Class: TEgFireGrid
property MinColumnWidth: Single;The narrowest a column can be made, in FireMonkey units: by its Width, by
dragging a title edge, or by AdjustColumnWidth.
The default is 10; the smallest value accepted is 1, so a column can
always be grabbed again to widen it.
Raising it does not widen the columns that are already narrower; RestoreMinimumColumnWidths
does. With AutoColumnWidth
on, changing it adjusts the columns at once.
