HTML Tables
HTML tables offer a powerful tool for presenting data on your website. But mastering them goes beyond just rows and columns. This article serves as your ultimate guide to unlocking the potential of HTML tables, stepping beyond the basics.
Prerequisites: HTML Introduction
What is HTML Tables?
An HTML Table is an arrangement of data in rows and columns in tabular format. Tables are useful for various tasks, such as presenting text information and numerical data. A table is a useful tool for quickly and easily finding connections between different types of data. Tables are also used to create databases.

Defining Tables in HTML
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 Cells
Table Cell are the building blocks for defining the Table. It is denoted with <td> as a start tag & </td> as a end tag.
Syntax
</td> Content...</td>
Table Rows
The rows can be formed with the help of combination of Table Cells. It is denoted by <tr> and </tr> tag as a start & end tags.
Syntax
</tr> Content...</tr>
Table Headers
The Headers are generally use to provide the Heading. The Table Headers can also be used to add the heading to the Table. This contains the <th> & </th> tags.
Syntax
</th> Content...</th>

Adding a border to an HTML Table
A border is set using the CSS border property. If you do not specify a border for the table, it will be displayed without borders.
Syntax
table, th, td {
border: 1px solid black;
}
Example: Addition of the border to the HTML Table.
<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;
}
</style>
</head>
<body>
<table style="width:100%">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
</tr>
<tr>
<td>Priya</td>
<td>Sharma</td>
<td>24</td>
</tr>
<tr>
<td>Arun</td>
<td>Singh</td>
<td>32</td>
</tr>
<tr>
<td>Sam</td>
<td>Watson</td>
<td>41</td>
</tr>
</table>
</body>
</html>
Output:
HTML Table with border
Adding Collapsed Borders in an HTML Table
For borders to collapse into one border, add the CSS border-collapse property.
Syntax
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
Example: Addition of Collapsed Borders in HTML.
<!-- index.html -->
<!DOCTYPE html>

</tr>
</table>
</body>
</html>

Adding Cell Padding in an HTML Table
Cell padding specifies the space between the cell content and its borders. If we do not specify a padding, the table cells will be displayed without padding.
Syntax
th, td {
padding: 20px;
}

<!-- index.html -->
<!DOCTYPE html>
<html>
<head>

}
th,
td {
padding: 20px;
}
</style>

Adding Left Align Headings in an HTML Table
By default, the table headings are bold and centered. To left-align the table headings, we must use the CSS text-align property.
Syntax
th {
text-align: left;
}
Example: Explains the text-align property where the text is aligned to the left.
<!-- index.html -->
<!DOCTYPE html>

Adding Border Spacing in an HTML Table
Border spacing specifies the space between the cells. To set the border-spacing for a table, we must use the CSS border-spacing property.

table {
border-spacing: 5px;
}
Example: Explains the border space property to make the space between the Table cells.
<!-- index.html -->
<!DOCTYPE html>
<html>

}
table {
border-spacing: 5px;

<td>32</td>
</tr>
<tr>
<td>Sam</td>
<td>Watson</td>
<td>41</td>
</tr>
</table>
</body>
</html>

Adding Cells that Span Many Columns in HTML Tables
To make a cell span more than one column, we must use the colspan attribute.
Example: Use of colspan attribute in HTML.
<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;

}
th,
td {
padding: 5px;
text-align: left;
}
</style>
</head>
<body>
<h2>Cell that spans two columns:</h2>
<table style="width:100%">
<tr>
<th>Name</th>
<th colspan="2">Telephone</th>
</tr>
<tr>
<td>Vikas Rawat</td>
<td>9125577854</td>
<td>8565557785</td>
</tr>
</table>
</body>
</html>
Output:

Adding Cells that span many rows in HTML Tables
To make a cell span more than one row, we must use the rowspan attribute.

<!-- index.html -->
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;

}
th,
td {
padding: 5px;
text-align: left;

<tr>
<td>8565557785</td>
</tr>
</table>
</body>
</html>
Output:

Adding a Caption in an HTML Table
To add a caption to a table, we must use the “caption” tag.
Syntax
<table style="width:100%">
<caption>DETAILS</caption>
Example: HTML Table caption by specifying the CSS properties for setting its width.
<!-- index.html -->
<!DOCTYPE html>
<html>
<head>

Adding a Background Colour to the Table
A color can be added as a background in an HTML table using the “background-color” option.

width: 100%;
background-color: #f2f2d1;
}
Example: Addition of the Table background color in HTML.
<!-- index.html -->

<body>
<table style="width:100%">
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>

<tr>
<td>Priya</td>
<td>Sharma</td>

</tr>
<tr>
<td>Arun</td>
<td>Singh</td>

</table>
<br />
<br />
<table id="t01">

<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>

<tr>
<td>Sam</td>
<td>Watson</td>

Creating Nested Tables
Nesting tables simply means making a Table inside another Table. Nesting tables can lead to complex tables layouts, which are visually interesting and have the potential of introducing errors.
Example: Nesting of HTML Table.
<!-- index.html -->
<!DOCTYPE html>
<html>
<body>
<table border=5 bordercolor=black>
<tr>
<td> First Column of Outer Table </td>
<td>
<table border=5 bordercolor=grey>
<tr>
<td> First row of Inner Table </td>
</tr>
<tr>
<td> Second row of Inner Table </td>
</tr>
</table>
</td>
</tr>
</table>
</body>
</html>
Output:
Nested HTML Table
