The difference between cellpadding and cellspacing

The difference between cellpadding and cellspacing: 1. The cellpadding attribute is used to set the distance between the cell content and the cell border, while the cellspacing attribute is used to set the distance between adjacent cells; 2. Cellpadding can Provide a certain blank area for the content in the cell, so that there is a certain gap between the content and the border, and cellspacing controls the size of the blank area between adjacent cells, making the table look more tidy and so on.

cellpadding and cellspacing are two attributes in HTML tables, used to control the spacing between cells in the table. Their differences are as follows:

cellpadding (cell inner margin):

The cellpadding property is used to set the distance between the cell content and the cell border.

It can provide a certain blank area for the content in the cell, so that there is a certain gap between the content and the border.

By setting the value of the cellpadding attribute, you can adjust the distance between the internal content of the cell and the cell border.

cellspacing (cell spacing):

The cellspacing property is used to set the distance between adjacent cells.

It controls the size of the blank space between adjacent cells to make the table look neater.

By setting the value of the cellspacing attribute, you can adjust the spacing between adjacent cells.

In summary, the cellpadding attribute is mainly used to control the distance between the internal content of the cell and the cell border, while the cellspacing attribute is mainly used to control the spacing between adjacent cells.

In HTML, you can achieve the corresponding effect by setting the values ​​of these two attributes in the table tag. For example:

<table cellpadding="10" cellspacing="5">
  <tr>
    <td>单元格1</td>
    <td>单元格2</td>
  </tr>
  <tr>
    <td>单元格3</td>
    <td>单元格4</td>
  </tr>
</table>

In the above example, cellpadding is set to 10 and cellspacing is 5, which means that the distance between the inner content of the cell and the border is 10 pixels, and the spacing between adjacent cells is 5 pixels.

It should be noted that the use of cellpadding and cellspacing attributes is no longer recommended in HTML5. Instead, CSS is used to control the style of the table. You can use the CSS padding and border-spacing properties to achieve similar effects. For example:

<style>
  table {
    border-spacing: 5px;
  }
  td {
    padding: 10px;
  }
</style>
<table>
  <tr>
    <td>单元格1</td>
    <td>单元格2</td>
  </tr>
  <tr>
    <td>单元格3</td>
    <td>单元格4</td>
  </tr>
</table>

The same effect as cellpadding and cellspacing can be achieved through the border-spacing attribute and padding attribute in the CSS style sheet.

In short, cellpadding and cellspacing are attributes used in HTML tables to control the distance between the internal content of a cell and its border, as well as the spacing between adjacent cells. Their use can make tables more beautiful and easier to read. But in HTML5, it is recommended to use CSS to control table styles instead of relying on these two properties.
