Practical CSS3 tables with rounded corners. There has been some discussion in the past about how/when to use tables in web development.
Though, the conclusion is the same: when you're dealing with tabular data, tables are absolutely required. Designing a table is a challenge - and here I'm not talking only about the way it looks. It's (mostly) about how easy is your table to read. If your table isn’t easy to scan, usually users get annoyed as they lose focus when trying to find the right column and row.
