Look at http://twitter.github.com/bootstrap/#tables. Examine "Example: Bordered table" table, the last cell in the first row has a border radius in the top right that shouldn't be there.
In "Example: Zebra-striped" both the first and last cells of the first row have border radii that shouldn't be there.
This fixes these problems by applying border radius values only when the tbody is the first child of the the table element. Put another way, only if the table doesn't have a header row will the border radius values be applied to the cells in the top row.
