[BUG] `lux.LuxDataFrame(df)` not working as intended #367

Closed westernguy2 closed 3 years ago

westernguy2 commented 3 years ago

Describe the bug Pandas DataFrame is able to make a copy of the DataFrame by calling pd.DataFrame(df). This is not the case for LuxDataFrame.

To Reproduce I encountered this error using the following code:

import pandas._testing as tm
df = tm.makeDataFrame()
lux.LuxDataFrame(df)

The output DataFrame is

while it should be showing up as

This bug doesn't happen in all cases, only some cases. For example

df = pd.read_csv('lux/data/car.csv')
lux.LuxDataFrame(df)

works as expected.

Thanks for report this issue @westernguy2! Do you think this might be a result of the index column not being the typical ordered IntIndex, but something that looks like a result of set_index called on a column? It might be worth seeing if other such dataframes works or breaks.

Yes, that is probably the reason this is happening, since that seems to be the main difference between the two examples. I will take a closer look at the index, thanks!
