Table being stretched through text

Hello,
I have a table at a certain size in which stores fetched text.
Only when someone does lots of letters in one single line it stretches the table accross the page.
If possible i want to do it so that the text automatically goes into a line break when it reaches the end of the table.

Hows this done?

have you set the table width and cell width if not try that first

This is the table here,
I have set it up to be 99% width of the page. But when someone does one big line of text, it stretches the whole table.
