Tables, or Rows and Columns?

I’ve got lots of tabular data to display in some quite complex ways in my app over the coming weeks…

… so much more than just a standard bootstrap 4 table generator creates… some columns have an input, some you can click on, some have their own little repeat inside.

I’ve never really used tables before - I’ve always just used rows and columns.

What do you see are the trade-offs of using tables versus rows and columns?
