I have created a simple table within a word document. For some unknown reason the cell seem to have an internal margin - text i enter in the cell starts to wrap about 1/2 way across the cell. I have gone into cell properties and reset margins to 0 and checked "same as" - no change. I have checked to see if maybe there are actually two cells - nope. I have never had this happen before. I am editing a document that I received from a colleague - so I imagine there is some sort of formatting I cannot see or find. I am not working with an existing table though. - (correction from previous post) - there is another recurring table in the document - one row and five columns that appears to line up with where I am having a problem. But my table clearly only has three wider columns and the tables are not connected. Any ideas?

If you click on the pilcrow (¶) from the HOME ribbon, you should be able to see all formatting markings that may be askew. (And, I agree that it probably is a formatting issue). If you still have issues maybe you can upload a portion of your file that is giving you the problem (removing any sensitive data)....You do that via the "Go Advanced" button at the bottom of each reply message.

Thanks Jim, that surfaced the formatting issue. In the meantime I made a workaround- made the table in other document and then pasted it in.
