Data Table and Table edit

bgnumis

I have copied this code from:

https://www.baulphp.com/datatables-usando-tabledit-con-php-ajax

I want to use fixedColumn but no way, I think it is because the code is old, but no way to fix the columns...

Can you help what should I add to fix the left column? And the fist row "header" of the table?

This is the third time you have asked the same question. You already had the answer here:
