The image below demonstrates the issue. (using Word from 'Microsoft office 365 Apps' product is up to date at the time of post)
The gap is due to special characters and an equation input. It's most visible at the bottom, where the table isn't even on both sides (as circled).
Unfortunately, it is minor for now... however, progressively, it becomes worse as the gap increases. Super annoying, the text on the left needs to align with the right within the table (as shown by the red line). I've attempted to use the ruler and table properties but haven't had any luck trying to fix it. However, I ran into a solution regarding the addition of cells and blank borders, which unfortunately doesn't meet the documents' future needs.
I couldn't find anything anywhere regarding a direct resolution to the issue.
Any help is much appreciated.
(Edit: the table is correctly formatted and aligned, the borders go to the end of the page on each side)
