Hello Natasha K,
I’m Segunfunmi, an Independent Advisor and Microsoft user like you. Thanks for posting the query here in this forum.
To repeat a table header row in Word 365, you need to right-click in the row that you want to repeat, click Table Properties, and in the Table Properties dialogue box, on the Row tab, select the Repeat as header row at the top of each page check box. Then select OK. Note that repeated table headers are visible only in the Print Layout view or when you print the document.
If you’re still having trouble, there could be a few reasons why the header row is not repeated. Any break in the table will prevent the header row from repeating. Make sure that the table is not wrapped (on the Table tab of Table Properties, text wrapping should be set to None) and that the only row(s) marked as a header row(s) is/are at the top of the table and consecutive. Also, if you’re viewing the table in Draft or Web Layout view, you will see the header row only once.

I hope this helps! Let me know if you have any further questions.
Kind Regards
