Is there any way to set the width of dynamic columns created in excel output using rtf template?

I am facing with an issue where I need to display around 70-80 columns dynamically in an excel output using the rtf template. I am able to get the columns however, the width of the columns is giving an issue. The column width is too small that I have to adjust the size of rows and columns in the excel output manually. I was wondering is there any way that I can specify the width of those dynamic columns?

I am using - for-each-group@column feature of the rtf in order to display the columns dynamically.

I am getting the output as attached in the image.
