     17   name="result",

File C:\SDK\Python311\Lib\site-packages\mstrio\project_objects\datasets\super_cube.py:332, in SuperCube.add_table(self, name, data_frame, update_policy, to_metric, to_attribute)
    330 if to_attribute is not None:
    331     if any(col for col in to_attribute if col not in data_frame.columns):
--> 332         raise ValueError(
    333             "Column name(s) in `to_attribute` were not found in"
    334             " `DataFrame.columns`."
    335         )
    336     else:
    337         table["to_attribute"] = to_attribute

ValueError: Column name(s) in `to_attribute` were not found in `DataFrame.columns`.

Steps to Reproduce

1. Create a data frame containing Korean (object name, element value)
df={'col1':[1,2,3,4],'한글':['aa','bb','cc','dd'],'ENG':['AA','가','나','BB'],'국어':['가','나','AA','BB']}
result=pd.DataFrame(df)
result
col1    한글    ENG    국어
0    1    aa    AA    가
1    2    bb    가    나
2    3    cc    나    AA
3    4    dd    BB    BB

2. If the object name is in Korean, the value cannot be retrieved (Blank), and if the result values of the object is in Korean, it is output as UTF-8 code (Unicode Escape Sequence) in the preview page.
