E.g. when passing a variable with a numeric value of 0, the colspan attribute is not rendered:
td colspan: @colspan, "Hello"
BTW, this also happens on the original CoffeKup.
thanks for letting me know. Will get this fixed when I have a moment.
I am not able to recreate this issue. There was a monkey patch implemented to address Issue #53 that may have fixed this problem. Are you still experiencing the issue? If so, can you supply a more specific example of when this is happening?
