Is nested table still problem for google ?? I mean i think now days crawler can easily read complex html tables .... Am i right ??
Yes, this shouldn't be a problem although it's not ideal. However, using CSS is the more efficient way to do it nowadays.
Use tables for tabular data. Use CSS for layout. Simple as that. Tables are not bad, it's just that they can be used badly
not a problem on SE. It's ideal to use CSS since it's more lighter in weight and bot can easily visit them.
Tables were never really much of a problem for search engines. The problem came from people who were using assistive and "non-traditional" browsing devices (such as mobile phones) trying to access the content on those sites. Anyway, at the end of the day you should be building sites for your users, not the search engines. They'll find it anyway, and the easier you can make it for people with mobile phones, PDAs, screen readers and text-based browsers to access and use your site, the easier it'll be for the search engines to crawl and index your site.
No Problem,Table is fine It wrould be better use css for layout.As you know GOOGLE like css ,MORE THEN TABLE.
Google does NOT LIKE CSS more than tables. It doesn't care one way or another. If you don't believe me, I have a few links to Matt Cutts' blog (he works for Google) I can show you if you like.
