I have a simple, multi-page table that is currently defined by

\setuptables[bodyfont=9pt]
\starttables[|l|p(15pc)|]

The problem is that the text in the cells on the right that have more than one line is set almost solid and is often too close to the next row.

So how can I adjust/control the vertical spacing both between and within rows?

\setuptables[bodyfont=9pt,\setupinterlinespace[line=2.4ex]]
gets:
! Missing \endcsname inserted.

                   \def

                                [line

                                                  ]

I apologize if this is a FAQ: my review of the wiki and of core-tab.tex has been most instructive, but not on this issue.
