Advantages:
1. Clean code, no redundant tags.
2. Separation of styles and structures (for convenience, styles are inline, and can be referenced externally when implementing applications.)
3 . Use JS to control the row-by-row color change of the table
4. Support the highlighting of selected items
5. Support the all-select/cancel function of the checkbox
6. The paging labels have been completed, and there is no background code (will be added in the future) Time update)
