Class: TEgFireGridColumn
property Width: Single;
Width of the column, in FireMonkey units; the default is 100. A value
below the grid’s MinColumnWidth
is raised to it. The user changes it by dragging the title’s edge (with
egoColumnResize), and AdjustColumnWidth
changes it when the columns fill the grid’s width.
The column is laid out on whole device pixels, so its drawn width may
differ from Width by a fraction of a unit.
