1. You can specify the minimum cell width using .cellWidthMin property (in pixels). If the automatically calculated cell width is smaller, the .cellWithMin value is used instead (and a horizontal scrollbar will be displayed).

The purpose of .heightSpec = "Parent100Pct" is not to adjust the row height. It sets the total height of the control (similar to .width = "100%"). Depending on the number of rows, this will either show a blank space below the last row or a vertical scrollbar.
