# Adding or editing columns

You can add new columns to the tabs in the Results Table or modify the properties of existing columns.

To add a new column to a tab or modify an existing column:

1. Access the Grid Preferences Editor.
2. In the Tab/Column pane, do one of the following:
   - To add a new column, click the tab in which you want to add the column and then click the New Column button. Note that you can add columns to the Grid tab.
   - To edit an existing column, click the column name.
   In either case, the Column Properties dialog is displayed.

3. Configure the column properties via the fields in the Column Properties dialog:
   - Property Name sets the property or dimension whose value will be displayed in this column. The display name of the property or dimension will be used as the name of the column tab.
   - Text Format determines how the value is displayed: `Plain` (the value displays as-is), `HTML`, `Integer`, or `Currency`.
   - Width sets the width of the column in pixels.
   - Text Separator sets the separator to use if the column has multiple values.
   - Cell CSS Class is currently not supported.
   - Disable Tooltip lets you show or hide the mouse-over tool tip for the column.
4. If desired, you can change the position of the column by dragging it up or down within the Tab/Column pane.
5. Click Apply to apply your changes to the component.
