Cannot Set Heading Rows in a Table

Sandra has a table that spans several pages. When she designates the first row as the "Heading Row," Word tags ALL the rows as heading rows. If she then deselects "Heading Row" (on any row, whether the first row or not), ALL the rows are deselected.

This obviously is not normal behavior for Word. If you select a row or two and indicate that those rows should be treated as heading rows, Word should repeat only those rows at the top of each page. The only condition that might explain this behavior is if the table is nested inside another table. You can't successfully set heading rows on individual rows of a table that is within another table.

If this is the case, then the solution is to "unnest" the tables. You need to copy the inner table, paste it into an area of the document that is outside of any other tables, and then get rid of the outer table. You should then be able to format the heading rows as desired.
