Setting the readonly property to true makes the cell value disappear

Hi, i have a strange behavior in my code
I'm trying to add dynamically a column to my jexcel instance,
Everything is fine for the first added data, I can set columns to readonly.
When i set my column to readonly, the value of the cells disappears, it is not present in the DOM either. But the value is still passed in the method excel.setRowData.

This is the dynamic object that I construct and I pass as a property of my column. If I change readonly to true, the value of the cells concerned disappears.

This is where I add the raw data, in rawdata object i can see the value but nothing in my sheet view.

I would really appreciate it if anyone has a solution to this problem 😃.
thanks in advance 🙏

Start by reproducing the issue with the dynamically constructed column object, readonly: true, and the excel.setRowData call described in the report. Compare the raw data with the rendered sheet and confirm that readonly cells retain their visible values and DOM content.
