Tabler is a Google Sheets add-on that allows you to set table styles in just one click.

Applying color to alternate rows makes your spreadsheet data easier to read. This is why using alternating colors is important in avoiding headaches and optimizing how quickly you can follow the data in front of you. 

With Tabler, this is quick and simple to apply by formatting your data as a table. 

If you aren’t happy with the color used for the row shading, you can change it.

if none of these style suit your preference or purpose, you can customize your sheet by creating your own table style.
