Need Help Regarding Html

Hi,
 
This is Sandeep, I am an web designer.
I had gone through the Html Validator and Css Validator provided by w3.org
My Website Url is : www.sandeepthi.com <http://www.sandeepthi.com/> 
When I validate my website I found that in css there are no bugs.
As in Html coding I am getting some bugs. 
Mainly, I am aware to see some bugs like :
In <table left spacing=0,..>
Its showing that left spacing is not used in table and also height.
 
I request you to help me in this process, according to w3 we have to keep
them or not.
 
Have a Nice Day.
 
Thanks & Regards,
G.V.Sandeep,
