Insert always the same custom table

Hi everyone!

I’ve looked in many Forums but I couldn’t find an answer to my problem:

I am building a website where I want to display different entrys but every entry has to have a table which is styled the same way: In the first column there are two rows, in the second culumn there are 4 rows in the third column there are 8 rows. Every entry has another content in the table. Is there a function or a plugin which can insert this pre-defined table?

The preson who will use the webiste is not familiar to plugins (like Tablepress) or html and can’t style tables by himself (e.g. rowspan,…). So I want that he can insert very easily this pre-designed table so that he just has to insert the content in the table.

I use the theme Accesspress ray.

Thank you in advance!
