a problem with tables, PLEASE HELP ME :/

[mohsen123]

hi there
I have around 60 pages in word, there is some tables and some characters in each table, I must change their size to 13 but when I make them bigger the characters will enter to the next line, I want them to fill the free spaces while changing the size and stay in their line.
I attach one of my pages, change them to 12-13 and watch what happening!


PLEASE, PLEASE give me the best solution while I'm not professional in Microsoft word



many thanks
