The `<td>` tag is used to define a data cell within a table. In this tutorial, we will cover the basics of the `<td>` tag and how it is used.
Syntax:
The basic syntax of the `<td>` tag is as follows:
<td> Cell content </td>
The `<td>` tag is always used within a `<tr>` tag, which defines a row in the table.
Attributes:
The `<td>` tag can have several attributes. Here are some of the commonly used attributes:
– `align`: This attribute is used to specify the horizontal alignment of the content within the cell. The possible values are `left`, `center`, and `right`.
– `valign`: This attribute is used to specify the vertical alignment of the content within the cell. The possible values are `top`, `middle`, and `bottom`.
– `colspan`: This attribute is used to specify the number of columns that the cell should span. For example, `colspan=”2″` would make the cell span two columns.
– `rowspan`: This attribute is used to specify the number of rows that the cell should span. For example, `rowspan=”2″` would make the cell span two rows.
Example:
Let’s create a simple table with two rows and two columns using the `<table>`, `<tr>`, and `<td>` tags:
<table>
<tr>
<td>Row 1, Cell 1</td>
<td>Row 1, Cell 2</td>
</tr>
<tr>
<td>Row 2, Cell 1</td>
<td>Row 2, Cell 2</td>
</tr>
</table>
This will create a table with two rows and two columns, with each cell containing some text.
Now, let’s add some attributes to the `<td>` tags to see how they work:
<table>
<tr>
<td align=”center” rowspan=”2″>Row 1, Cells 1-2</td>
<td>Row 1, Cell 3</td>
</tr>
<tr>
<td align=”right”>Row 2, Cell 3</td>
</tr>
</table>
In this example, the first cell in the first row spans two rows (`rowspan=”2″`) and is centered horizontally (`align=”center”`). The second cell in the first row is a regular cell with no attributes. The third cell in the second row is aligned to the right (`align=”right”`).
Conclusion:
In conclusion, the `<td>` tag is used to define data cells within a table. It can have several attributes to control the appearance and behavior of the cell. By using the `<td>` tag along with the `<tr>` and `<table>` tags, you can create tables to display data on your website.
