How to center the html table

HTML, as a markup language, is widely used to build web pages. Among them, tables are an important element for organizing data and layout. When designing tables, centering is a commonly used style to make the page more beautiful and readable. This article will introduce how to achieve the centering effect of HTML tables through CSS style sheets.

1. Knowledge related to HTML tables

In HTML, the table tag is used to define the table, the tr tag is used to define the rows of the table, and the td tag is used to define the cells. We can use CSS style sheets to change the style of elements, including table layout, color, borders, etc.

2. Horizontal centering

1. Use the text-align attribute

You can use the text-align attribute to horizontally center the text. For example:

table{

text-align:center;

}

This will center all text content within the table label, regardless of which cell it is located in.

2. Use the margin attribute

We can also use the CSS margin attribute to achieve horizontal centering. You can add the following style to the outer element of the table:

table{

margin: 0 auto;

}

This will center the table horizontally within its containing element, regardless of its size and location. This method works for centering a single table at a time.

3. Vertical centering

1. Use the vertical-align attribute

We can also use the vertical-align attribute of CSS to achieve vertical centering, which can be done in Set it in the style of the cell or table (header), for example:

td{

vertical-align: middle;

}

This will vertically center the content in the cell. If set in the header (th), the header will be vertically centered.

Note: Using the vertical-align attribute can only be set in the cell, not on the table itself.

2. Use the line-height property

You can achieve vertical centering by using the line-height property of CSS. For example:

td{

line-height: 100px;

}

Set the cell height to 100px and then set the row height to 100px, which will center the cell's content vertically. Note that this method only works for a single row of data.

Conclusion

Through CSS style sheets, we can easily achieve the centering effect of HTML tables. For most designers and developers, the horizontal centering method is relatively easy, while the vertical centering method can be more difficult. It is recommended that you try different methods to find the one that works best for your specific scenario.
