how to align tables?
<table style="float:left"> Or: <table style="display:inline-block">
I did not understand you. Do you want to make two columns?
For example, <table align="center"></table>
and how to two table in one line?
like in facebook there are three tables in one line , not a columns , :-)
put the tables inside div, e.g. make one div and make further divs equal to number of tables, now put your table inside each div.
you have to study html5.there is rule for that concept you are talking.
