Your image suggests you have a table that's been composed on rows copied/pasted from other tables with different alignments. Either that or you have some serious table corruption going on.

Assuming it's the latter, corrupt tables can often be 'repaired' by converting the tables to text and back again or by cutting & pasting them to another document, saving that document in RTF format, closing the document then re-opening it and copying back to your original document.

If it's the former, you'll need to:
• turn off any 'around' text wrapping;
• split the table wherever there's a disjunction of the alignments; and
• make sure all the split tables have the same alignment, non-wrap settings and indents.
Once you've done that, you can re-join them. To delete the intervening paragraphs between the tables so you can re-join them is no more difficult than selecting them and pressing Delete.
