1Definition and Usage

The tableLayout attribute is used to display algorithm rules for table cells, rows, and columns.

①This attribute specifies the layout algorithm used to complete table layout.

②The fixed layout algorithm is faster, but not very flexible.

③The automatic layout algorithm is slower, but it better reflects the traditional HTML table.

2 Fixed table layout

① Compared with automatic table layout, the browser is allowed to layout the table faster;

② Its level The layout only depends on the table width, column width, table border width, cell spacing, and has nothing to do with the content of the cell;

③ By using a fixed table layout, the user agent can Show table.

3 Automatically determine the table layout

①The width of the column is set by the widest content in the column cell without folding;

②Because it needs to access all the contents in the table before determining the final layout, this algorithm sometimes takes a long time.

4table-layout attribute value

①automatic: (default value) column width is set by the cell content;

②fixed: column width is set by the table Width and column width settings;

③inherit: Specifies that the value of the table-layout attribute should be inherited from the parent element.

Note: All browsers support the table-layout attribute.

Any version of Internet Explorer (including IE8) does not support the attribute value "inherit"! ! !

5 Theory is not as good as practice, and the code can be run

No matter how much you say, it is better to understand it faster by looking at the code~ Let’s take a look at this chestnut together↓↓↓

(For the convenience of everyone to see the code, I wrote the CSS and HTML code together)

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8">
        <title>table-layout属性测试</title>
        <style type="text/css">
            table.tb1 {
                table-layout: automatic;
            }
            table.tb2 {
                table-layout: fixed;
            }
        </style>
    </head>
    <body>
        <table class="tb1" border="1" width="100%">
            <tr>
                <td width="20%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
                <td width="40%">bbbbbbbbbbbbb</td>
                <td width="40%">ccc</td>
            </tr>
        </table>
        <br />
        <table class="tb2" border="1" width="100%">
            <tr>
                <td width="20%">aaaaaaaaaaaaaaaaaaaaaaaaaaaaa</td>
                <td width="40%">bbbbbbbbbbbbb</td>
                <td width="40%">ccc</td>
            </tr>
        </table>
    </body>
</html>

After running, you will see the following picture Shown:

I want to explain here that maybe your browser is wide enough, maybe your cell does not have enough content, and you may not be able to see both. At this time, you need to reduce the width of the browser or increase the content of the cell, and you will see the different effects of the two attribute values~~~
