Edits the selected column's expansion options. If expand is true, the column expands in proportion to its expansion ratio versus the other columns' ratios.
For example, 2 columns with ratios 3 and 4 plus 70 pixels in available width would expand 30 and 40 pixels, respectively.
If expand is false, the column will not contribute to the total ratio.
