Hi LV_5458,
Do you mean you would like to overlap two cells instead of using Text box in Word? If so, I think you can right click on the small “Arrow” icon of the table, select “Table Properties”. Then under Table wrapping, select Around. After that go to Positioning > Check option “Allow overlap” and Ok to save. Then repeat the processes for another table of cells.
After that you can click on the small “Arrow” to move over to the position you would like the cell to overlap with like below screenshot.
Best regards,
Dihao
