This happens for the case where you have rowHeaders set as true.
See the demo: http://jsfiddle.net/semix/qm6mm696/
Note false is logged for the row header column part.
Please put a note of this in HOT, or maybe afterGetColHeader should not count in the row header column?
Hi @semix
I simplified the example here http://jsfiddle.net/rndud60k/ and it doesn’t show the false log anymore. It turned out that the columnSorting caused it to return false > http://jsfiddle.net/ttboungj/
I have reported on our Github board at https://github.com/handsontable/handsontable/issues/5071
I will update you as soon as it’s fixed.
