I can't get header rows to repeat in tables.

[Carpedyce]

When I create or edit a table and select 'Repeat as Header Row at the Top of
each Page' it does not work.

Remember, you must not put in page breaks, but let the table continue on. If
you break the table into separate tables (as on separate pages), you lose the
header function.

You can use "Page break before" formatting on a row to break a table without
splitting it (the heading row(s) will continue). And note that the heading
row(s) must be at the top of the table and contiguous. Make sure you don't
have any non-heading rows selected when you apply this formatting.
