If the table takes more than a page, you can't unless you resize it.
I assume you do not want the row breaking across pages.
If so, select it and change the row properties to not allow it to break across pages.
To prevent a table row from splitting across pages in Microsoft 365 Word, you can follow these steps:
- Click anywhere inside the table that you want to modify.
- Click on the "Layout" tab in the ribbon at the top of the screen.
- Click on the "Properties" button in the "Table" group.
- In the "Table Properties" dialog box, click on the "Row" tab.
- Check the box next to "Allow row to break across pages" to uncheck it.
- Click "OK" to close the dialog box.
To resize it, you probably will want to choose a smaller font or resize your columns but I cannot really tell without looking at the actual document.
On the other hand, if you simply want more of the table on the first page, you would want to mark the row that gets moved to a new page to allow it to break across pages.
