# 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]
