You can use the Column Editor to set or change the name, data type, default value, and other properties of a table column. To set the focus to a needed cell of a grid, use the mouse click. Also you can move through the grid using Tab and Shift + Tab keys.
To set or change the name, data type, default value and comment of a column, activate the appropriate cell and type the desired value.
To set or unset flag-type column properties (
NULL, auto incremented, flags), select or deselect the
corresponding check boxes. The set of column flags depends on the
data type of the column.
To reorder columns, index columns or foreign key columns in the Column Editor, select the whole column to reorder by clicking the selector column on the left of the column grid. Then move the column by using Control+Up (to move the column up) or Control+Down (to move the column down) keys.
To delete a column, select it by clicking the selector column on the left of the column grid, then press the Delete button on a keyboard.
