This dialog is activated by selecting the command Column Options... from the Table Menu. At least one column must be selected.
The checkbox Enumerate all to the right can be used to build the name of all the columns which are at the right of the selected one. If the name of the selected column is "xyz", this column and the following ones will be renamed to "xyz1", "xyz2", and so on.
The buttons "<<" and ">>" are used to change the selected column. Remain that the highlighting of the column in the table behind the dialog box will not change. Therefore, the column to which the formatting commands are applied is the one whose name appear in the "Column Name" box.
The Plot Designation selector is used to define the column which is used for X values. Only one column in each table can be selected for X, then if another column was already selected, its plot designation will become "none".
