Hello, I am trying to set the cell span data of a power table in a python script like this:

cell_span_headers = ["row", "column", "width", "height"]
cell_span_data = []
for i in xrange(0, dataset.getRowCount(), 6):
	cell_span_data.append([i, "Enabled", 1, 6])
cell_span_data = system.dataset.toDataSet(cell_span_headers, cell_span_data)
power_table = event.source.parent.getComponent("Power Table")
setattr(power_table, "Cell Span Data", cell_span_data)

When I run this code I get the following error

16:48:37.640 [AWT-EventQueue-0] ERROR com.inductiveautomation.ignition.client.util.gui.ErrorUtil - <HTML>Error executing script for event:&nbsp;<code><b>actionPerformed</b></code><BR>on component:&nbsp;<code><b>Write L3Towers Targets to Tag</b></code>.

Is there a better way to set the cell span data of a power table?

Take a closer look at the proper property name:

https://docs.inductiveautomation.com/display/DOC81/Vision+-+Power+Table#VisionPowerTable-Properties

{ Names in the property editor are "prettied up" for the user. Hover over them to get the "scripting name", or look at the documentation. }

If you get an error that says a particular property doesn't exist, you either don't have the object you think you have, or you've misunderstood/mistyped the name.

Also, if you are trying to use setattr() to set an attribute that has a not-valid-for-python-or-java name, take that as a hint.

Thanks! I've been searching for the property name and didn't know where to look. That's a huge help.
