The Headers tab enables you to specify the maximum length of the labels or descriptions for members and member lists. You can specify different lengths for different dimensions.
The Headers tab also contains the Other text box, which has two uses:
If syntax is added for the HeaderOption keyword but the syntax is not exposed through a new control in the Headers tab, you can specify that syntax in Other.
If the form contains invalid syntax for the HeaderOption keyword for a dimension, the Other text box displays that syntax.
