Question

how to create colspan in html

Answer 1

Use rowspan if you want to extend cells down and colspan to extend across. You can use rowspan="n" on a td element to make it span n rows, and colspan="m" on a td element to make it span m columns. Looks like your first td needs a rowspan="2" and the next td needs a colspan="4" 

Answer 2

I hope helpful for you.
