On the page, the layout is completed through the nesting of tables. That is, a table can be embedded into another table. The reason is as follows: first, the layout of the web page is complex, and an external table is required to control the overall layout. If some internal typographical details are also implemented through a summary table, it is easy to cause conflicts such as the Row Height and column width, which makes table creation difficult. Secondly, the layout is completed by nesting tables on the page. That is, a table can be embedded into another table. The reason is as follows:
First, the layout of a Web page is complex. A table layout is required externally. If some internal typographical details are also implemented through a summary table, it is easy to cause conflicts such as the Row Height and column width, which makes table creation difficult.
Secondly, when parsing a webpage, the browser downloads the entire table structure before displaying the table. If Nesting is not used, the table is very complex. It takes a long time for the viewer to see the content of the webpage.
For these reasons, nested tables are introduced. The total table is responsible for the overall layout, and the nested table is responsible for the layout of each sub-column, and inserted to the corresponding position of the total table. In this way, they perform their respective duties and do not conflict with each other. Example: 10-47.htm
