When I open this document in MS Word, it displays it but shows the message: "A table in this document has become corrupted".
This RTF document is erroneous. Some RTF readers may display it, but it is not guaranteed.

How was this document created? If you want, I can find what's exactly wrong in it, but I do not promise loading it.
