Solve the following python programming problem given the following code:
def buildOlv(self) : 
    columns = [ColumnDefn ('DataValue', 'left', (- 1), minimumWidth = 100, valueGetter = 'dataValue', valueSetter = self.valueSetterDataValue, imageGetter = self.imgGetterDataValue, stringConverter = self.str2DataValue, headerImage = 'star'), ColumnDefn ('Date', 'left', (- 1), minimumWidth = 120, valueGetter = 'date', imageGetter = self.imgGetterDate, cellEditorCreator = self.dateEditor, headerImage = 'star'), ColumnDefn ('Time', 'left', (- 1), minimumWidth = 100, valueGetter = 'time', imageGetter = self.imgGetterTime, cellEditorCreator = self.timeEditor, stringConverter = self.localtime2Str, headerImage = 'star'), ColumnDefn ('UTCOffset', 'left', (- 1), minimumWidth = 100, valueGetter = 'utcOffSet', imageGetter = self.imgGetterUTCOffset, headerImage = 'star'), ColumnDefn ('CensorCode', 'left', (- 1), valueGetter = 'censorCode', minimumWidth = 110, cellEditorCreator = self.censorEditor, imageGetter = self.imgGetterCensorCode, headerImage = 'star'), ColumnDefn ('ValueAccuracy', 'left', (- 1), valueGetter = 'valueAccuracy', minimumWidth = 100, imageGetter = self.imgGetterValueAcc), ColumnDefn ('OffsetValue', 'left', (- 1), valueGetter = 'offSetValue', minimumWidth = 100, stringConverter = self.offSetValue2Str, imageGetter = self.imgGetterOffSetValue), ColumnDefn ('OffsetType', 'left', (- 1), valueGetter = 'offSetType', minimumWidth = 100, imageGetter = self.imgGetterOffSetType, cellEditorCreator = self.offSetTypeEditor), ColumnDefn ('QualifierCode', 'left', (- 1), valueGetter = 'qualifierCode', minimumWidth = 130, imageGetter = self.imgGetterQualifier, cellEditorCreator = self.qualifierCodeEditor), ColumnDefn ('LabSampleCode', 'left', (- 1), valueGetter = 'labSampleCode', minimumWidth = 130, imageGetter = columns.imgGetterlabSample, cellEditorCreator = self.labSampleEditor)] 
    self.SetColumns (columns) 
    self.SetObjects (None) 
    def rowFormatter(listItem, point) : 
        'Formats each row to have a larger font than the default font.

            :param listItem:
           ...

    
    

    Fix the buggy line: columns = [ColumnDefn ('DataValue', 'left', (- 1), minimumWidth = 100, valueGetter = 'dataValue', valueSetter = self.valueSetterDataValue, imageGetter = self.imgGetterDataValue, stringConverter = self.str2DataValue, headerImage = 'star'), ColumnDefn ('Date', 'left', (- 1), minimumWidth = 120, valueGetter = 'date', imageGetter = self.imgGetterDate, cellEditorCreator = self.dateEditor, headerImage = 'star'), ColumnDefn ('Time', 'left', (- 1), minimumWidth = 100, valueGetter = 'time', imageGetter = self.imgGetterTime, cellEditorCreator = self.timeEditor, stringConverter = self.localtime2Str, headerImage = 'star'), ColumnDefn ('UTCOffset', 'left', (- 1), minimumWidth = 100, valueGetter = 'utcOffSet', imageGetter = self.imgGetterUTCOffset, headerImage = 'star'), ColumnDefn ('CensorCode', 'left', (- 1), valueGetter = 'censorCode', minimumWidth = 110, cellEditorCreator = self.censorEditor, imageGetter = self.imgGetterCensorCode, headerImage = 'star'), ColumnDefn ('ValueAccuracy', 'left', (- 1), valueGetter = 'valueAccuracy', minimumWidth = 100, imageGetter = self.imgGetterValueAcc), ColumnDefn ('OffsetValue', 'left', (- 1), valueGetter = 'offSetValue', minimumWidth = 100, stringConverter = self.offSetValue2Str, imageGetter = self.imgGetterOffSetValue), ColumnDefn ('OffsetType', 'left', (- 1), valueGetter = 'offSetType', minimumWidth = 100, imageGetter = self.imgGetterOffSetType, cellEditorCreator = self.offSetTypeEditor), ColumnDefn ('QualifierCode', 'left', (- 1), valueGetter = 'qualifierCode', minimumWidth = 130, imageGetter = self.imgGetterQualifier, cellEditorCreator = self.qualifierCodeEditor), ColumnDefn ('LabSampleCode', 'left', (- 1), valueGetter = 'labSampleCode', minimumWidth = 130, imageGetter = columns.imgGetterlabSample, cellEditorCreator = self.labSampleEditor)]
