The Dimensions tab of Table Editor allows you to define dimensions for the table, if necessary.
Dimensions for columns or groups of columns are used to cluster table data.
Right-click within the Dimensions area to display the context menu allowing you to add a new dimension, edit or drop dimensions.
Dimension management tools are also available through the Navigation bar of Table Editor.
The Dimension Editor dialog allows you to select a field or a group of fields that will be treated as one dimension.
To select a field, you need to move it from the Available Fields list to the Selected Fields list. Use the buttons or drag-and-drop operations to move the fields from one list to another.
