Removing sortable headers of a bootstrap table

This went wrong some days ago, so yesterday I thought I give it a try again while recording it: https://www.useloom.com/share/2000be5d6b854bcfbd865af348ff9bee

As you can see this went totally wrong, and I’m not sure why.

Before removing the sort I had copied the whole code, so that I could paste it again after removing the sort. But that also did not work in this case. Luckily when closing wappler it reverted back to the old setting.
