About Creating Header and Footer Titles
When working with tables containing multiple segments, you can place a title at the top of each segment (as a header) or at the bottom of each segment (as a footer).
When creating titles, remember the following rules:
• Two-directional repeat regions cannot have titles.
• For single-row headers and footers, you must select the row twice for the first and second rows.
• A table can have only one header and one footer.
• When selecting rows to be used in a title, you cannot choose a row that is part of a repeat region.
• Two titles cannot intersect each other. That is, when creating a new title, you cannot select a portion (one or two rows) of an existing title to be used in the new title. However, you can define the same rows to be both the header and the footer of the same region or to be titles of a number of regions.
• You cannot create a header or footer title in a row that has cells merged in a column.
