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.

</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>

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>
Example 1: Creating a simple table in HTML using a table tag.
<!-- index.html -->
<!DOCTYPE html>
<html>

</table>
</body>

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.

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>

</html>
Output:
Adding Collapsed Borders in an HTML Table
For borders to collapse into one border, add the CSS border-collapse property.

Syntax
table {
border-spacing: 5px;

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

Adding Cells that Span Many Columns in HTML Tables

<style>
table,
th,
td {
border: 1px solid black;

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>
