Put method with overwrite 'True' clears cell styling.

[markand]

I have an excel file, using it to populate data for users. The excel file has some cell styling like borders, cell alignments etc.
I am using this lib to populate data, however, I see that once data is populated, the styling is cleared.
I call the Put method with 'overwrite' param set to 'true' to populate the excel sheet.
Is there any workaround or solution to keep styling?
