Strange spacing in table

There is a really weird gap in the middle of my cell table. It seems to be caused by the table going over the page, but I’m unable to determine how to fix it. Picture included.

A screenshot does not allow to peek at the structure and formatting of the document. Attach an anonymised sample. Mention OS name (Mint 17 according to the tags?), LO version and save format (.odt from the window title bar?).

by anonymised sample do you mean replace the text with nonsense or is their something else I should be doing in addition to that? i tried to google the term but couldnt find anything specific

Anonymise: ensure there is no private information which leaks on the internet. So it can be nonsense about your private data, “lorem ipsum” in narrative paragraphs or totally random characters. It’s up to you to decide which data you accept to disseminate.

But make sure the same problem is still there in the sample.

Anonymizing a document - general

Not a solution:
Seems to be text pasted from an external source; see the blue degree symbol at the end of each paragraph.
Instead of the B column (the central one), you can add padding to one or both columns with content.
