[Twisted-Python] woven dynamic table cell updating

I have some code (attached ui.py) that creates a table displaying results
of running tasks.  The rows are tasks and the columns are step numbers in
that task.  I use this table when I make a bunch of requests into PB
servers running on multiple machines.  As those tasks move forward, the
PB server calls back into the client (which has a perspective_* method)
to update the status of that task/step.  An 'I' appears for 'in
progress', 'S' for 'success', and 'F' for 'failure'.  If there are
failures, I display the details once the entire table is populated and
all tasks are complete.

      | 1 | 2 | 3 | 4 | 5 | status
task1 | S | S | S | S | S | success
task2 | S | S | I | I | I | in progress
task3 | S | S | I | I | I | in progress
task4 | S | S | I | I | I | in progress
task5 | I | I | I | I | I | in progress

In the console based version each time the PB server task calls back into
the client to update the status, it also requests that the client
redisplay the screen.  So the screen redraws quite often.  Does anyone
know how I could do something similar with woven?  My thought was that
this will require LivePage, but I'm not sure.  Anyone have any
thoughts/suggestions?  I've attached (in widgets.py) my first attempt at
porting the results table to woven.

Thank you.
