printing a formatted multiplcation table
I want write a PHP code to print multiplication table with a certain format. attached is the format i want.
how it works--You have two cells spanned together and the result of those two are are multiplied with the column. this will give you the X like structure in the table.
I have included a code that will only print a multiplication table without that format.

May you please clarify what problem you are encountering? I just inputted two sample variables:
$start_num=4;
$limit=20;
And it generates your multiplication matrix just fine....
