Specifies the number of rows that will be repeated on each printer page with this table.
property HeadingRowCount: Integer;
(introduced in version 1.7)
If these rows overlap next rows (due to cell merging), this property is ignored on pagination.
A special color (HeadingRowColor) can be applied to heading rows (even if they overlap next rows). If HeadingRowCount=0, this color is applied to the first row.
