Detailed explanation of how to remove borders from CSS tables

Removing borders from CSS tables is a very basic technique in front-end development. It can effectively improve the beauty of the table and make it more consistent with the page design style. In actual work, we often need to remove the borders of tables. This article will explain in detail the method of removing borders from CSS tables.

1. The basic structure of CSS tables

Before starting to learn how to remove borders from CSS tables, let’s first understand the basic structure of CSS tables. The basic structure of a CSS table is divided into four basic elements: table (table), table row (tr), table cell (td) and header cell (th). Among them, table rows (tr) and table cells (td) are required, while header cells (th) can be added according to actual needs.

The following is a basic CSS table structure:

<table>
  <tr>
    <th>表头单元格</th>
    <th>表头单元格</th>
  </tr>
  <tr>
    <td>表格单元格</td>
    <td>表格单元格</td>
  </tr>
  <tr>
    <td>表格单元格</td>
    <td>表格单元格</td>
  </tr>
</table>

2. Methods for removing borders from CSS tables

The method for removing borders from CSS tables is relatively simple, and you can use the following two methods :

1. Use the border attribute to be set to 0

When we set the border attribute to 0, the border of the table will be removed.

table, tr, td {
  border:0;
}

2. Use the border-collapse attribute to set it to collapse

The border-collapse attribute is used to set the merging method of table borders. When set to collapse, the borders of the table will be merged, thereby achieving the effect of removing the borders of the table.

table {
  border-collapse:collapse;
}

3. CSS table spacing processing

When we use the above two methods to remove the table border, there may be a certain spacing between the cells of the table, resulting in the aesthetics of the table affected. In order to solve this problem, we can use the padding property of CSS to adjust the cells of the table.

table {
  border-collapse:collapse;
}
td {
  padding:0;
}

4. Other adjustments to CSS table styles

In addition to removing borders and spacing from tables, we can also make other adjustments to table styles according to actual needs.

1. Setting the table width

We can use the width attribute to set the width of the table, or use percentages to adjust the relative width.

table {
  width:100%;
}

2. Adjustment of vertical alignment of table cells

Sometimes, the content of table cells is not much, and vertical alignment problems will occur. We can use the vertical-align attribute to adjust table cells.

td {
  vertical-align:middle;
}

3. Processing of header cells

Header cells usually require special processing, and you can set the font boldness, background color, etc.

th {
  font-weight:bold;
  background-color:#f2f2f2;
}

5. Summary

Removing borders from CSS tables is a very basic skill in front-end development. Mastering this skill can effectively improve the beauty of the table.
