Zebra stripes of uitableview

The effect is similar to that of the table on the webpage, rendering different background colors for the odd and even rows in the table respectively, so that the background color of the adjacent two rows of data is staggered, enhance the user's visual experience. Previously, I used cellforrowatindexpath to customize the cell background based on the row value of indexpath when generating the cell. I learned a trick here today, which can also be put in tableview: willdisplayforcell: forrowatindexpath.

Thanks to azure_sagi, the display misspelled accidentally. Thank you.
