Single or multiple columns and rows can be selected, cleared, inserted, deleted and autosized. All such functions work on the columns or rows in the current selection. Therefore, if just a single cell is selected only that column or row would be impacted, but if an entire row is selected for a column function then all the columns in the grid will be impacted. All these functions are accessible from either the Edit menu or the grid's popup menu, which is accessible by clicking the right mouse button on the grid.
A column can be automatically re-sized to the width of the longest text its cells contain. This functionality is available via the menus, but can be quickly accessed by double clicking on the column dividing lines in the title row. Columns can also be re-sized to the widest cell in a selection, as opposed to the widest cell in the entire column. This functionality is available from the menus.
