[Excel export] Cannot merge already merged cells

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.

Hi Dan,

Apologies for the late reply - I was trying to find out exactly when this happens. I seem to have the issue in the Gantt only when I have scale = “Week” set.

I set:

gantt.scale = 'Week';
gantt.cellWidth = 100;
gantt.useEventBoxes = 'Never';
gantt.cellDuration = 1440;
gantt.cellGroupBy = “Month“;
gantt.cellWidth = 100;
gantt.cellWidthSpec = “Fixed“;

And have two headers:

• A month header (level 0, groupBy = “Month“)

• A week header (level 1, groupBy = “Week“)
  

The call stack is:
