Code Snippet - Summing Values in a Column
# This example script would be added to a button that is in the same container as the table you are working with. 
# It grabs the data of the Table component, and adds up the values in the first column, displaying the result to the user.
  
# Get a Table component's data.
table = event.source.parent.getComponent("Table")
data = system.dataset.toPyDataSet(table.data)
  
# Loop through the data, summing the Value column.
value = 0.0
for row in data:
   value += row[0]
  
# Show the user the sum of the Value column.
system.gui.messageBox("The value is: %f" % value)
