Structure of the table
When you use a table for layout, you can divide the table into headers, bodies, and footers, specifically is as follows:
<thead></thead>: The header used to define the table must be in the <table></table> tag, which typically contains the page's head information such as logos and navigation.
<tfoot></tfoot >: Footer for defining a table, in <table></table> tags < After the thead></thead> Mark , it usually contains the enterprise information at the bottom of the webpage.
<tbody></tbody>: The body used to define the table, located in the <table></table> tag <tfoot ></tfoot > tag, it usually contains the contents of the page except the head and the bottom.
Colspan Merge same row rowspan merge same column

Form controls: Contains specific form feature items, such as a single-line text entry box, password entry box, check box, submit button, reset button, and so on.
Tip: A form often needs to contain descriptive text that prompts the user to fill out and manipulate.
form fields: He is the equivalent of a container that accommodates all form controls and prompt information, through which he defines the URL address of the program used to process the form data , and how the data is submitted to the server. If you do not define a form field, the data in the form cannot be transferred to the background server.
