How to use CSS to hide tables

In front-end development, tables are one of the commonly used elements, but sometimes we need to hide some of the rows or columns in order to hide unnecessary content or optimize the user experience. So, how to use CSS to hide the table?

CSS is a style sheet language that can be used to control the layout, fonts, colors, etc. of HTML documents. CSS has great advantages when it comes to table hiding. Below we will introduce several commonly used methods of hiding tables.

1. Use display:none

First, we can use the display:none attribute to hide rows or columns in the table. The specific implementation method is to select the row or column labels to be hidden and add the display:none attribute so that they are not displayed on the page.

For example, the following table contains 5 cells:

<table>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
  </tr>
</table>

If we want to hide the third cell, we can select the td label where it is located and add the display:none attribute :

<table>
  <tr>
    <td>1</td>
    <td>2</td>
    <td style="display:none;">3</td>
    <td>4</td>
    <td>5</td>
  </tr>
</table>

In this way, the third column in the table is hidden.

2. Use visibility:hidden

Using the visibility:hidden attribute can also hide rows or columns in the table. The difference from display:none is that using the visibility:hidden attribute can hide the element but retain its occupied space, while using display:none does not retain it.

The following is an example: we want to hide the 2nd row in the table:

<table>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td>4</td>
    <td>5</td>
  </tr>
  <tr style="visibility:hidden;">
    <td>6</td>
    <td>7</td>
    <td>8</td>
    <td>9</td>
    <td>10</td>
  </tr>
</table>

In this way, the 2nd row in the table is hidden.

3. Use opacity:0

In addition to using display:none and visibility:hidden, you can also use the opacity:0 attribute to hide rows or columns in the table. This method is similar to visibility:hidden and can also retain the space occupied by the element.

For example, we want to hide the 4th cell:

<table>
  <tr>
    <td>1</td>
    <td>2</td>
    <td>3</td>
    <td style="opacity:0;">4</td>
    <td>5</td>
  </tr>
</table>

In this way, the 4th column in the table is hidden.

Summary:

The above three methods can effectively hide rows or columns in the table, but which method to use needs to be chosen according to the specific situation. If you only need to hide the element without retaining the position, use display:none; if you need to retain the position, use visibility:hidden or opacity:0. Either way, they all need to be implemented using CSS.

Beyond this, there are ways to hide tables using script libraries like JavaScript or jQuery, but this is beyond the scope of this article. I hope the methods introduced above can be helpful to you.
