HTML Table

The table is defined with <table></table> tag and a table is divided into row with <tr></tr> tag and row is divided into column with <td></td> tag. The <td>content</td> tag contain can contain page content. Please see structure below.
<table>
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>

Now I will introduce with you with the table tags and their attributes.

Table Border:

You have to define a table border size to display the table area or hide the table area [ie border=0.]. Please see example below.

Code Result 
<table border="0">
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
Note: The table area is disappear; due to the border "0" value.

<table border="1">
   <tr>
      <td>Place your content here.</td>
   </tr>
</table>
1st TD 2nd TD 
<table border="3">
  <tr>
    <td>Place your content here.</td>
  </tr>
</table>

<table border="5">
   <tr>
      <td>Place your content here.</td>
   </tr>
</table>

Table Width:

We can use width by percentage or fixed. Let's experiment with table width.
Code Result 
<table boreder="1" width="50%">
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
50% 50% 
<table border="3" width="100%">
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
100% 100% 
<table border="200">
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
Note: We are using fixed width [width="200"] here.

Table Cellspacing:

Cellspacing create width between border lines.
Can be used to put space between cells / objects in invisible tables [If you use border="0"]

  </tr>
</table>
cellspacing="0" cellspacing="0"

  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
cellspacing="1" cellspacing="1" 
<table border="200" cellspacing="3">
 <tr>
    <td>Place your content here.</td>
 </tr>
</table>
cellspacing="3" cellspacing="3"


Table cellpadding:

Cellpadding create minimum space between objects and the inner table border.

cellpadding="0">
  <tr>
      <td>Place your content here.</td>
  </tr>
</table>
cellpadding="0" cellpadding="0" 
<table border="3" width="100%" cellspacing="1"
