[NTG-context] TABLE 'last line' tag?

Hello, When formating tables the first row (top of the header) is easily formated by using for example: \setupTABLE[row][1][rulethickness=0.90pt,topframe=on] I was wondering whether there's an equivalent for specifically addressing the LAST row in a table? Something along the lines of \setupTABLE[row][last][rulethickness=0.90pt,topframe=on] \setupTABLE[row][-1][rulethickness=0.90pt,topframe=on]%python-like which both don't work ... Thanks for any hint, Joh
