The width of the two main columns (Caption and Value) used in the Form View and Form Edit.
A comma separated list containing the width in pixels of each column.
Only two widths can be specified here, the width of the Caption column and the width of Value column.
E.g.
FormCellWidths="100,400" sets the width of the Caption to 100 and the width of the cell holding input fields to 400. The width of the Input fields can not be controlled using FormCellWidths! To set the width of Input fields, see the SetEditField method.
