I did the manual way and it works fine for me.
I check the value from ALL rows in column 4 and sum it to a variable.
function totalWeight() {
var weightTotal=0;
for (var i=0; i<(tableData.getNumberOfRows()-1); i++)
{
weightTotal += tableData.getValue(i, 4);
}
tableData.setValue(tableData.getNumberOfRows()-1, 4, weightTotal);
}
