Hello. I need to represent floats in jTable formatted. When I do tbl.model.add_row [obj, 1.3524632478].to_java, obj is represented as it's to_s method's return value, but float do not. Overriding float's to_s method does nothing. I want floats to be formatted like this class Float def to_s sprintf("%.2f", self) end end in all my tables.
