Making text wrap in WP

I have a website

I tried to make a custom home page using tables because I’m not good with CSS.

My problem is that my text does not wrap by itself. Depending on the browser, some of the text is cut off on the right. I have to go in manually and add
to make my text look correct (not cut off on the right)

Is there an easy fix for this other than learn css?

The person for whom I made the site adds text to the center portion of the home page. It is too cumbersome for her to have to make the text layout properly by messing around with the html.
