HTML Tables

---

An HTML table is defined with the <table> tag.

Each table row is defined with the <tr> tag. A table header is defined with the <th> tag. By default, table headings are bold and centered. A table data/cell is defined with the <td> tag.

<table style="width:100%">
    <tr>
        <th>Firstname</th>
        <th>Lastname</th> 
        <th>Age</th>
    </tr>
    <tr>
        <td>Jill</td>
        <td>Smith</td> 
        <td>50</td>
    </tr>
    <tr>
        <td>Eve</td>
        <td>Jackson</td> 
        <td>94</td>
    </tr>
</table>

---

Note: The <td> elements are the data containers of the table.

They can contain all sorts of HTML elements; text, images, lists, other tables, etc.

---

If you do not specify a border for the table, it will be displayed without borders.

A border is set using the CSS border property:

table, th, td {
    border: 1px solid black;
}

---

Cell padding specifies the space between the cell content and its borders.

If you do not specify a padding, the table cells will be displayed without padding.

To set the padding, use the CSS padding property:

th, td {
    padding: 15px;
}

---

By default, table headings are bold and centered.

To left-align the table headings, use the CSS text-align property:

th {
    text-align: left;
}

---

Border spacing specifies the space between the cells.

To set the border spacing for a table, use the CSS border-spacing property:

table {
    border-spacing: 5px;
}

Note: If the table has collapsed borders, border-spacing has no effect.

---

To make a cell span more than one column, use the colspan attribute:

<table style="width:100%">
    <tr>
        <th>Name</th>
        <th colspan="2">Telephone</th>
    </tr>
    <tr>
        <td>Bill Gates</td>
        <td>55577854</td>
        <td>55577855</td>
    </tr>
</table>

---

To make a cell span more than one row, use the rowspan attribute:

<table style="width:100%">
    <tr>
        <th>Name:</th>
        <td>Bill Gates</td>
    </tr>
    <tr>
        <th rowspan="2">Telephone:</th>
        <td>55577854</td>
    </tr>
    <tr>
        <td>55577855</td>
    </tr>
</table>

---

To add a caption to a table, use the <caption> tag:

Note: The <caption> tag must be inserted immediately after the <table> tag.

<table style="width:100%">
    <caption>Monthly savings</caption>
    <tr>
        <th>Month</th>
        <th>Savings</th>
    </tr>
    <tr>
        <td>January</td>
        <td>$100</td>
    </tr>
    <tr>
        <td>February</td>
        <td>$50</td>
    </tr>
</table>

Note: The <caption> tag must be inserted immediately after the <table> tag.
