Tables are defined with the <table> tag. A table is
divided into rows (<tr>), and each row is divided into
cells (<td>). The cell can contain text, images, lists,
paragraphs, forms, horizontal rules, tables, etc.
<table> <tr> <td> </td> </tr> </table>
Border: If you do not specify a border attribute the table will be displayed without any borders. Sometimes this can be useful, but most of the time, you want the borders to show.
To display a table with borders, you will have to use the border attribute:
<table border="1"> <tr> <td> </td> </tr> </table>
Width: You can specify the width of the table either in percentage or pixel.
<table border="1" width="100%" > <tr> <td> </td> </tr> </table>
<table border="1" width="100%" cellspacing="0" cellpadding="0"> <tr> <td> </td> </tr> </table>
