719 - Frame: Either 0 or 1 row or column wide, depending on whether the table
720 style has an outer border on each side. The frame cells are always
721 empty and marked as TABLE_CELL_PADDING.
723 - Title: Either 0 or 1 row high.
725 - Layers: Usually, one row for each layer dimension, but less if a layer
726 dimension is empty (has no value).
728 - Body and data: Variable (and can be empty).
730 - Caption: Either 0 or 1 row high.
732 - Footnotes: From zero rows up to the number of footnotes in PT (only
733 footnotes referenced in the other regions are shown).
735 The title, layers, caption, and footnote Region join all the body's
736 columns into single cells.
