I have created a user defined template function called format_index with 1 argument. Here is the code:
Code:
def evaluate(self, formatter, kwargs, mi, locals, val):
return re.sub('\.00', '', format_number(field(val), '[[0:05.2f]]'), flags=re.I)
The template in the custom column looks like this:
{series_index:format_index()}
Unfortunately I get the following error:
TEMPLATE ERROR global name 're' is not defined
Any idea what the problem is?
