CSS to fix long lines of text with no spaces that push columns to the right

I have a table with a 45% width column on the left and a 55% width column on the right.

When a user types in "MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM" for testing, it pushes the first column into the space designated for the right column and runs it off the page, so now I have to fix it.

Even this website breaks it nicely and still allows a dynamic width. But I don't know how they did that.

I have tried adding this style to it to fix it, but it doesn't work:
.LongLineWrap {
   white-space: pre-wrap;      /* CSS3 */  
   white-space: -moz-pre-wrap; /* Firefox */    
   white-space: -pre-wrap;     /* Opera <7 */  
   white-space: -o-pre-wrap;   /* Opera 7 */    
   word-wrap: break-word;      /* IE */

I believe someone said they had to have a fixed width left panel.

Is there a fix for this? So it doesn't break the look and feel, other than telling people not to do that?

I think what you are looking for is "overflow: hidden;" .   https://www.w3schools.com/cssref/pr_pos_overflow.asp
I think you want a combination of word-wrap and break-word:
