Thanks for ur reply,
But still the requirment is not fulfilled. My requirement is
1. A table , in that only one row and one column.table no 1.
2. OK. Inside that table, I am placing another table with 3 rows and 3 columns, this is table no2.For this table I am giving Cell spacing as 1.eg <table cellspacing=1>.
3. If I give table no 1 bgcolor= red means , the Inner table will be tablised. using the cellspacing the outline of table 2 will be red.
4. this thing I want to make it in CSS , all other attributes I gave in CSS its working only this cellspacing is pending,
I tried the above 2 steps given above, but It didnt come, I want to give that attribute in a class and call it for some particular table only I want to use.
this is my requirement
