Basic Usage >

table-layout: fixed; To apply a property to a table, specify it in CSS as follows:

table {
width: 100%; /* Specify the width of the table */
table-layout: fixed;
}

When this property is applied to a table, the column width is determined based on the content and size of the cells in the first row. Then, in the other rows in the table, the column width determined in the first row is applied as it is, and it is fixed regardless of the size of the contents.

Specifying Column Width

table-layout: fixed; You can also specify the column width individually in CSS. This is done by applying styles directly to <colgroup> and <col> tags, or th, td tags.

<table>
<colgroup>
<col style="width: 50%;" >
<col style="width: 30%;" >
<col style="width: 20%;" >
</colgroup>
<!-- table contents -->
</table>

This method allows you to precisely control the width of each column.

Advantages >

Improved performance: Faster rendering because the browser no longer has to load the entire contents of the table and calculate the column width.
Layout Stability: Fixed column widths make table layouts more predictable. This will prevent layout issues such as wrapping text in the table.

Notes

If the content in the table does not fit within the specified column width, it can cause text to wrap or be hidden. Therefore, you need to specify the appropriate column width or use the overflow property to address this.
If you expect consistent behavior across all browsers, it's important to check browser compatibility as well.

table-layout: fixed; By making good use of properties, you can significantly improve the appearance and performance of your web page's tables.
