HTML Tables are used to arrange data systematically so that the user can easily interpret it. With lots of data being available, the developers need to organize it in a manner so that it can be easily understood; tables facilitate this efficiently. They are widely used for research, data analysis, etc.
Uses-
- The schema of the databases is well defined with the help of tables.
- It helps in easy comparison of lots of data available.
- Tables help in the systematic presentation of information and content available.
- Tables consist of rows and columns and can contain text, images, links, other tables, etc.
Defining tables in HTML
The <table> element is used to create a table in HTML. Table header is defined by <th> and by default, the table headings are bold and centered. The <tr> tag is used for rows and <td> is used to define table data or cell.
For example,
Code-
<!DOCTYPE html>
<html>
<body>
<table style="width:100%">
<tr>
<th>FirstName</th>
<th>LastName</th>
<th>Age</th>
</tr>
<tr>
<td>Shreya</td>
<td>Mishra</td>
<td>24</td>
</tr>
<tr>
<td>Jai</td>
<td>Singh</td>
<td>32</td>
</tr>
<tr>
<td>Philip</td>
<td>Watson</td>
<td>41</td>
</tr>
</table>
</body>
</html>

1. Adding border
The CSS border property is used for setting the border.

border: 1px solid black;
}
</style>
</head>
<body>
<table style="width:100%">

border: 1px solid black;
border-collapse: collapse;
}

border: 1px solid black;
border-collapse: collapse;

Similarly, it is possible to add an image as the background.
10. Nesting Tables
Nesting means one within another i.e., two or more tables within a single table. For example,
Code-
<!DOCTYPE html>
<html>
<head>
<style>
#t1{
padding: 10px;
border-collapse: collapse;
height: 200px;
}
#t2{
padding: 10px;
border-collapse: collapse;
height: 200px;
}
</style>
</head>
<body>
<table id="t1" border="3">
<tr>
<td>
First Column
</td>
<td>
<table id="t2" border=3>
<tr>
<td>
First row
</td>
</tr>
<tr>
<td>
Second row
</td>
</tr>
</table>
</td>
</tr>
</table>
</body>
</html>
Output-
Table Header, Body, and Footer
We can define a table with a header and footer (that remains the same) and the body consisting of the main content. The tags are-
- <thead> – It is to create the header.
- <tbody> – This helps to create the main body part.
- <tfoot> – It is to create the footer.
A table can contain various <tbody> tags but only one <thead> and <tfoot>.
For example,
Code-
<!DOCTYPE html>
<html>
<head>
<title>Table</title>
<style>
table,tr,td{
padding: 10px;
border-collapse: collapse;
}
</style>
</head>
<body>
<table border = "1" width = "100%">
<thead>
<tr>
<td colspan = "4">Header</td>
</tr>
</thead>
<tfoot>
<tr>
<td colspan = "4">Footer</td>
</tr>
</tfoot>
<tbody>
<tr>
<td>Data 1</td>
<td>Data 2</td>
<td>Data 3</td>
<td>Data 4</td>
</tr>
</tbody>
</table>
</body>
</html>
Output-
Table Heading
The <th> tag is used to specify a heading to a table. By default, it is bold and centered. It can be used to replace the <td> tag.
Code-
<!DOCTYPE html>
<html>
<head>
<style>
#tab1{
border-collapse: collapse;
border-spacing: 3px;
}
</style>
</head>
<body>
<table id="tab1" border="1px" width="100%">
<tr>
<th>FirstName</th>
<th>LastName</th>
<th>Age</th>
</tr>
<tr>
<td>Shreya</td>
<td>Mishra</td>
<td>24</td>
</tr>
<tr>
<td>Jai</td>
<td>Singh</td>
<td>32</td>
</tr>
<tr>
<td>Philip</td>
<td>Watson</td>
<td>41</td>
</tr>
</table>
</body>
</html>
Output-
Table Height and Width
The width and height attributes of a table can be specified using percentage or pixels.
Code-
<!DOCTYPE html>
<html>
<head>
<style>
#tab1{
border-collapse: collapse;
border-spacing: 3px;
}
</style>
</head>
<body>
<table id="tab1" border="1px" width="400px" height="500px">
<tr>
<th>FirstName</th>
<th>LastName</th>
<th>Age</th>

<td>Jai</td>
<td>Singh</td>
<td>32</td>
</tr>
<tr>
<td>Philip</td>
<td>Watson</td>
<td>41</td>

Summary
HTML Tables are of utmost importance for the systematic representation of data. In this article, we’ve looked at the creation of tables using the <table>, <tr> and <td> tags. We’ve also looked at the formatting of tables using CSS, such as setting alignment, padding, border-collapse, background, caption, column and row spanning, etc. We’ve also discussed the nesting of tables and the use of header and footers in a table.
