Tabel

• The < table> element is used to add tables to a web page.
• A table is drawn out row by row. Each row is created with the < tr> element.
• Inside each row there are a number of cells represented by the < td> element (or < th> if it is a header).
• You can make cells of a table span more than one row or column using the rowspan and colspan attributes.
• For long tables you can split the table into a < thead>, < tbody>, and < tfoot>.
