The Table Configuration Preview section of the page is used to configure the actual table layout and select the cells for configuration. The Display Name for the table can also be keyed in this section. This is shown just above the table when the table is rendered.

Moving the mouse over the cells highlights the cells with a red dotted border. Clicking the cell then selects it so that the settings for that cell can then be configured – the cell is then highlighted with a red solid border.
