Questions about using tables to store data in web standards and changing the background color of cells

This example mainly aims to illustrate the problem of using tables to store data in web standards. If there is a large amount of data to be processed on the page, as long as your page uses Div + CSS layout, data can be stored in tables. The web standard does not allow the use of tables. By the way, the background color of a cell is changed. Here is a typical Div + CSS layout, where the data generated by PHP is stored in a table. 

 
Tr. sfhover {color: #999999; Background: # f9f9f9;} tr {Background: # eeeeee;} table {border: solid 1px #336699 ;}
