When i am using nested headers that time i needs new column in that new column updating neighbor column data. It is not coming as empty header cell. How to get empty header column? after clicking on insert column option.
You’d need to update
colHeaders to get an empty header name.
I wanted to create a demo for you but apparently there’s an issue with
updateSettings method being called inside the
afterCreateCol/beforeCreateCol hooks. None of my workarounds helped. I will keep you notified about the progress on that issue.
