tabSequnece in a table view

I can set the tabSequence on the columns in a table view form and once loaded, tab through the columns in the first row only. When you are on the last column, then press tab again, it selects the first column of the first row again. How can I get this to work so that if a user is on the last column and presses tab it moves to the second row first column and so on?

Thanks,

Keith
