I had someone show me this empty box at the bottom of the table on their Microsoft Word 2013 document and tell me that they didn't know how it got there or how to remove it.
I know it's not a cell from the table above as when I right click on it, it doesn't bring up options for dealing with cells. I've tried selecting it and deleting it and then right clicking on it and cutting or deleting it, but no luck. What is causing this and how do I remove it?
