5.      Create a function ValidateSizeField to validate the depth/size field. Use onChange event in this function.

6.      Create a function GenerateTables and write the code to generate math tables.

7.      Create a function DisplyTable and write the code to display a math table on HTML page.

8.      To create HTML elements with the help of JavaScript pass HTML code to document.write( ) function as string. For example if you want to create HTML table with the help of JavaScript write

document.write( “<table border="1"><tr><td>1</td><td>2</td></tr><tr><td>3</td><td>4</td></tr></table>” );
