In the page, typesetting is done through the nesting of tables. That is, one form can be nested within another form. Here’s why:
First of all, the layout of the web page will be very complicated, and an external table is needed to control the overall layout. If some internal layout details are also implemented through the master table at this time, it will easily cause conflicts in row height, column width, etc., making table production difficult.
Secondly, when the browser parses the web page, it displays the table after downloading the entire table structure. Without nesting, the table would be very complex and the viewer would have to wait a long time to see the content of the web page.
For these reasons, nested tables are introduced. The main table is responsible for the overall layout, and the nested table is responsible for the layout of each sub-column and inserted into the corresponding position of the main table. In this way, each performs his or her duties without conflict with each other. File example: 10-47.htm
