Html tables with examples.

 HTML TABLES

The HTML tables allow web authors to arrange data like text, images, links, other tables, etc. into rows and columns of cells.

The HTML tables are created using the <table> tag in which the <tr> tag is used to create table rows and <td> tag is used to create data cells. The elements under <td> are regular and left aligned by default

Example


<!DOCTYPE html>
<html>

   <head>
      <title>HTML Tables</title>
   </head>
	
   <body>
      <table border = "1">
         <tr>
            <td>Row 1, Column 1</td>
            <td>Row 1, Column 2</td>
         </tr>
         
         <tr>
            <td>Row 2, Column 1</td>
            <td>Row 2, Column 2</td>
         </tr>
      </table>
      
   </body>
</html>

Here the border is an attribute of <table> tag and it is used to put a border across all the cells. If you do not need a border, then you can use border = "0".

Table Heading

Table heading can be defined using <th> tag. This tag will be put to replace <td> tag, which is used to represent actual data cell. Normally you will put your top row as table heading as shown below, otherwise you can use <th> element in any row. Headings, which are defined in <th> tag are centered and bold by default.

Example


<!DOCTYPE html>
<html>

   <head>
      <title>HTML Table Header</title>
   </head>
	
   <body>
      <table border = "1">
         <tr>
            <th>Name</th>
            <th>rollnumber</th>
         </tr>
         <tr>
            <td>anjula</td>
            <td>5</td>
         </tr>
         
         <tr>
            <td>dhiroo</td>
            <td>7</td>
         </tr>
      </table>
   </body>
   
</html>


Cellpadding and Cellspacing Attributes


There are two attributes called cellpadding and cellspacing which you will use to adjust the white space in your table cells. The cellspacing attribute defines space between table cells, while cellpadding represents the distance between cell borders and the content within a cell.

Example


<!DOCTYPE html>
<html>

   <head>
      <title>HTML Table Cellpadding</title>
   </head>
	
   <body>
      <table border = "1" cellpadding = "5" cellspacing = "5">
         <tr>
            <th>Name</th>
            <th>Roll number</th>
         </tr>
         <tr>
            <td>anjula</td>
            <td>5</td>
         </tr>
         <tr>
            <td>dhiroo</td>
            <td>7</td>
         </tr>
      </table>
   </body>
	
</html>

Clspan attribute if you want to merge two or more columns into a single column. Similar way you will use rowspan if you want to merge two or more rows.

Example


<!DOCTYPE html>
<html>

   <head>
      <title>HTML Table Colspan/Rowspan</title>
   </head>
	
   <body>
      <table border = "1">
         <tr>
            <th>Column 1</th>
            <th>Column 2</th>
            <th>Column 3</th>
         </tr>
         <tr>
            <td rowspan = "2">Row 1 Cell 1</td>
            <td>Row 1 Cell 2</td>
            <td>Row 1 Cell 3</td>
         </tr>
         <tr>
            <td>Row 2 Cell 2</td>
            <td>Row 2 Cell 3</td>
         </tr>
         <tr>
            <td colspan = "3">Row 3 Cell 1</td>
         </tr>
      </table>
   </body>
	
</html>

Tables Backgrounds

You can set table background using one of the following two ways −

  • bgcolor attribute − You can set background color for whole table or just for one cell.

  • background attribute − You can set background image for whole table or just for one cell.

You can also set border color also using bordercolor attribute.

Note − The bgcolor, background, and bordercolor attributes deprecated in HTML5. Do not use these attributes.

Example


<!DOCTYPE html>
<html>

   <head>
      <title>HTML Table Background</title>
   </head>
	
   <body>
      <table border = "1" bordercolor = "green" bgcolor = "yellow">
         <tr>
            <th>Column 1</th>
            <th>Column 2</th>
            <th>Column 3</th>
         </tr>
         <tr>
            <td rowspan = "2">Row 1 Cell 1</td>
            <td>Row 1 Cell 2</td>
            <td>Row 1 Cell 3</td>
         </tr>
         <tr>
            <td>Row 2 Cell 2</td>
            <td>Row 2 Cell 3</td>
         </tr>
         <tr>
            <td colspan = "3">Row 3 Cell 1</td>
         </tr>
      </table>
   </body>
	
</html>
