Detailed introduction to how to set up tables in HTML

In web design, tables are a commonly used formatting method, which can be used to organize and display data. In HTML, tables are defined and set up through tags. The following will introduce in detail how to set up tables in HTML.

1. Create a table

In HTML, a table is defined by the <table> tag. You can create a simple table through the following code:

<table>
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the <table> tag is used to define the table, and <tr> tags to define table rows, and <td> tags to define table cells. Among them, <td> represents the content of the cell, and each <td> label represents a cell.

2. Set the border of the table

In HTML, you can change the appearance of the table by setting the border of the table. You can change the border size of the table by setting the border attribute of the <table> tag. The code is as follows:

<table border="1">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the border attribute is set to 1, which means that the border size of the table is 1 pixel.

3. Set the width and alignment of the table

You can change the width of the table by setting the width attribute of the <table> tag. The code is as follows:

<table border="1" width="50%">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the width attribute is set to 50%, which means that the table width occupies 50% of the parent element.

You can change the alignment of the table by setting the align attribute of the <table> tag. The code is as follows:

<table border="1" width="50%" align="center">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the align attribute is set to center, which means that the table is aligned horizontally and centrally.

4. Set the background color and font color of the table

You can change the background of the table by setting the bgcolor attribute of the <table> tag color. The code is as follows:

<table border="1" width="50%" align="center" bgcolor="#E6E6FA">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the bgcolor attribute is set to #E6E6FA, which means that the background color of the table is lavender.

You can change the font color by setting the color attribute of the <td> tag. The code is as follows:

<table border="1" width="50%" align="center" bgcolor="#E6E6FA">
    <tr>
        <td>1</td>
        <td>2</td>
        <td>3</td>
    </tr>
    <tr>
        <td>4</td>
        <td>5</td>
        <td>6</td>
    </tr>
    <tr>
        <td>7</td>
        <td>8</td>
        <td>9</td>
    </tr>
</table>

In the above code, the color attribute of the <td> tag is set to red, which means that the font color is red.
