I haven’t had time to work on it. I think the answer is either to do this (per this post [Perspective table editing help](http://forum.inductiveautomation.com/t/perspective-table-editing-help/23738/6))

import json  
json.reads

columnJSON = ‘’  
columnSet = []  
for i in range(columnCount):  
columnSet.append(json.reads(columnJSON % ()))  
columnSet[i][‘field’] = ‘Column Name’

myTable.props.columns = columnSet

or maybe to choose the dataset to return as json. I’ve been tied up with other things so haven’t had a moment to try either solution.
