[Excel export] Cannot merge already merged cells

Asked by Leo
1 day ago.

Hi there,

We have implemented the Excel export functionality using ExcelJS for DayPilot.Gantt.
On some charts, the exports fail with the error “Cannot merge already merged cells“. We could however not find the common denominator yet.

Do you have any ideas?

Cheers
Leo

Hi Leo,

Most likely, it‘s related to the row headers (number of columns, column titles…). You can also try posting the error stack trace.
