Ghost Border

[Kimmy]

Hello.

I created the table from scratch. I need the 1st and 3rd cell to be have borders but the stubborn bottom border kept making the 2nd cell white.

First table - Applying color to all borders worked
Second table - Removing all borders worked
Third table - Adding bottom border on 1st and 3rd only. If you zoom in closely you can see the gridline for the 2nd cell SO technically there is no bottom border already BUT why in the world is it still white? D:

I've tried
1. manually placing each border under border&shading (experimented with border tab, page border tab, shading tab)
2. unchecking 'border line's in autocorrect
3. Borders on Page layout tab


4. I can't find the answer anywhere on google I can only find the grey line problem or the double border problem. Tried what they did also but it's not a horizontal line.


Solution I found BUT** I'm personally NOT ALLOWED to add a row below to use the top border instead. So I can only work with 1 row table
Please help.
