HTML table gets cut

Themes

Hello. I use the DAWN theme and have trouble with the HTML tables behaviour.
Here is how a clean HTML table behaves today.

I went to the theme - assets - CSS - general - basics.css file and edited the following:

table:not(.highlight) {
    width: 120%;
    border-collapse: collapse;
    font-size: 1.5rem;
    word-break: break-all;
}

word-break was set to “normal” and width to “100%”. Still it did not change anything.

Thank you for your help!
