Hey Tobias,
We just pushed v0.1.0 of the extension we’ve been working on this afternoon. There are very few FooTable data attributes supported right now but the mechanics was the most important. We’ll add more attributes later on.
Meanwhile, any feedback / suggestion are welcome. Here is the repo: https://github.com/ThemeAvenue/TablePress-FooTable
PS: Sorry for the username confusion, ThemeAvenue belongs to N2Clic, so we’re the same people ??
