A table is a two dimensional matrix, consisting of rows and columns. It can be used for more than just displaying a table of data. All table related tags are included between the <table>…</table> tags. Table rows can be of two types. A row that spans across columns of a table is called the header row. It is defined using <th>…</th> tags. Individual data cells placed in the horizontal plane creates a data row. Each row of a table is described between the <tr>…</tr> tags. Each column of a table is described between the <td>…</td> tags. The <table> tag takes the following attributes:

Align	Horizontal alignment is controlled by the Align attribute. It can be set to Left, Center or Right
VAlign	Controls the vertical alignment of cell contents. It accepts the values Top, Middle or Bottom
Border	Controls the border to be placed around the table. The border thickness is specified in pixels
Width	Specifies the width of the table in pixels or percentage
Cellpadding	Controls the distance between the data in a cell and the boundaries of the cell
Cellspacing	Controls the spacing between adjacent cells
Colspan	Combine more than one column
Rowspan	Combine more than one row

Tables need to be given a heading. Table headings are called Captions. Captions can be provided to a table by using the <caption> ….. </caption> tags. This tag have the align attributes. It controls placing of the caption in the table. It can be set to Top or Bottom.
