How to use CSS to hide tables

In front-end development, tables are a very common component used to display data. However, sometimes we don't want to display all the data, but need to hide a certain column or row. At this time, we need to use CSS to hide the table.

1. Hide table columns

1. Use the display attribute

We can use the display attribute in CSS to hide a column of the table. The specific steps are as follows:

First, set a special class name for the column that needs to be hidden. For example, we name the column we want to hide "hidden-column".

Then, in CSS, set

    .hidden-column { 
      display: none; 
    }

to the column corresponding to this class name so that this column will be hidden.

For example, the following is a simple table:

<table>
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <th>Email</th>
      <th>Phone</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Tom</td>
      <td>23</td>
      <td>tom@example.com</td>
      <td>(123) 456-7890</td>
    </tr>
    <tr>
      <td>Jane</td>
      <td>27</td>
      <td>jane@example.com</td>
      <td>(987) 654-3210</td>
    </tr>
    <tr>
      <td>John</td>
      <td>35</td>
      <td>john@example.com</td>
      <td>(111) 222-3333</td>
    </tr>
  </tbody>
</table>

If we want to hide the "Email" column of the table, we can do this:

td:nth-child(3),
th:nth-child(3) {
  display: none;
}

Here Use the CSS :nth-child() selector to specify which columns need to be hidden.

2. Use the visibility attribute

Another way to hide columns is to use the visibility attribute in CSS. The difference between it and the display attribute is that when we use the visibility attribute to hide a table column, the hidden column still occupies its original position on the page, but is invisible. When using the display attribute, the hidden column will be removed from the page. Removed from page layout.

The code here is also similar to the first method. ：

.hidden-column {
  visibility: hidden;
}

2. Hide table rows

To hide the entire table row, we can use a method similar to hiding columns.

1. Use the display attribute

Similar to hiding columns, we can also use the display attribute in CSS to hide table rows. The specific steps are as follows:

First, set a special class name for the row that needs to be hidden. For example, we name the second row that needs to be hidden "hidden-row".

Then, in CSS, set the row corresponding to this class name:

.hidden-row {
  display: none;
}

2. Use the visibility attribute

Similar to hiding columns, we can also use CSS visibility property to hide table rows. Likewise, a table row hidden using this method still occupies its original position on the page, but is no longer visible.

The code for using the visibility attribute to hide table rows is as follows:

.hidden-row {
  visibility: hidden;
}

3. Summary

The above is how to use CSS to hide table columns or rows. No matter which method you use, you can hide table cells or rows through specific HTML elements or CSS selectors. In the actual development process, understanding and using these techniques can better control the style and layout of tables and improve front-end development efficiency.
