The contents must be placed in the cell, the cell must be in the row, and the row must be placed in the table. When you set the row height and sizing of a cell, the corresponding row or column is affected at the same time

Cell Merging: (It is recommended to use table nesting as far as possible)

Colspan= "n" merges the same row of cells (followed by the code to subtract the corresponding column)

Rowspan= "n" merges the same column cell (minus the corresponding column starting from the second row)

3. Select input

radio button Group <input type= "Redio" name= "" checked= "Checked" value= ""/> name is used for grouping; Value value is not visible, is submitted to the program; checked, set default options.

check box group <input type= "checkbox" Name= "checked=" checked "value=" "/>

File upload <input type= "file" name= "id=" "/>

<lable for= "" ></lable>

The <label> tag defines the callout (tag) for the INPUT element.

The label element does not present any special effects to the user. However, it improves usability for the user of the mouse. This control is triggered if you tap text inside a LABEL element. That is, when the user selects the label, the browser automatically shifts the focus to the label-related form controls.

The For property of the <label> tag should be the same as the id attribute of the related element.

Drop-down list box

<select name= "" id= "" size= "" multiple= "multiple" >--size=1 when it is a menu; >1 is a list. Multiple is a multi-select.

<option value= "value" > Content 1</option>

<option value= "Value" selected= "selected" > Content 2</option>--selected, set as Default

<option value= "value" > Content 3</option>

</select>
