When setting Rows and Cols Sizes, You should remember that the user should with ease change row order and navigate in the sheet, this may be hard if those size are too big. Still if we have cells with images(min 100px) we should set an size which allows to view them in an good manner. Please use the following sizes for your columns and rows: Sizes [px]:
- 21( Height )
- 60( Formula Row , Height )
- 100( Image Cell, Height )
- 200
- 300
- 350( Formula Column Width )
