I need help to create a program that when the user input a number ( any number) the output will show the calculation table with results for that number.

If its going to be web based you'll need PHP + a server technology (Apache and IIS are common). If you're using Java you'll need a servlet; rather you'll likely [U]want[/U] a servlet.
Basically you'll use <table> which is a HTML element (not programming), which creates rows with <tr> and cells with <td>. They both have rowspan and colspan as possible attributes (so the # of cells can be less than width x height).
