Hi,
I need help.
I have an OPI BOY. I created a table Nx3, (Nrows, 3 columns), N can be from 1 to 200.
User can modify the table and when is ready press the button to write the whole column of the table to PV 
The PV is type of aao , size 200. Of course, the table can have less than 200 elements.
What would be the easiest way to do this?
I tried something like that, create an Action Button and as an action I execute such a script:

from org.csstudio.opibuilder.scriptUtil import PVUtil
from array import array

tab = display.getWidget("Table")

row = tab.getTable().getRowCount()
for i in range(1, row):
   PVUtil.writePV("$(PREFIX):ListVolt", i)  # - this works but write always one element [0]
   print i                                                          

My question:
How I can write one column of a table to PV which is type of aao?
Is it possible to write the whole column at once? Or I have to do it element by element?
Any help will be appreciated.

Regards
