Row or specific cell text alignment

Hi,

thanks for your post, and sorry for the trouble.

CSS is the correct way, you will then just need to adjust the selector part of the CSS command.
Basically, mix the code that you are currently using with the concepts from https://tablepress.org/faq/change-background-color-of-a-row/ and https://tablepress.org/faq/highlight-cells-or-content/
