Hi Ayush Paria
It all depends on the "Margin settings" on your spreadsheet and the "Column Width" you choose when you create the tables for your scenario
Following the steps in the picture,
With the default Column Width settings,
Normal Margin gives us 9 columns
...
Wide gives us 8 columns
Narrow gives us 10 columns
..
I hope this helps you and gives a solution to your problem
Do let me know if you need more help
Regards
Jeovany
