Substitute for HTML-tables

My users type text that is converted to HTML by using an editor. Now I have a problem with text in columns. Like the label Name [tab] and the name, [Enter] label Address [ tab] and the address and so on.

‌I can't use HTML-tables in RS by creating a textbox and a placeholder for HTML. They are just ignored. N‌ow I've tried several things as divs and spans. Nothing works.

A‌nyone any idea of how to do this? To do something similar in HTML that RS will understand?

‌I‌t's no option to use RS-tables (or I have to rebuild my programm).
