Bug summary

When trying to input a dataframe to a table, it will raise keyerror. Since cellText [0] will not give the first row of the dataframe and thus not returning the correct column length. So, I made a modification to recognize cellText as dataframe.
contact:chenxuw@alumni.cmu.edu

Code for reproduction

df=pd.DataFrame()#any dataframetable=table.table(ax,df,loc='center')

Actual outcome

Traceback (most recent call last):
File "C:\Users\053232\AppData\Local\Programs\Python\Python38\lib\site-packages\pandas\core\indexes\base.py", line 3653, in get_loc

The above exception was the direct cause of the following exception:

Expected outcome

return a table contains a dataframe

Additional information

Check we have some cellText

if cellText is None:    # assume just colours are needed    rows = len(cellColours)    cols = len(cellColours[0])    cellText = [[''] * cols] * rowselif isinstance(cellText, pd.DataFrame):    # 获取DataFrame的列名    column_names = cellText.columns.values    cellText = np.vstack([column_names, cellText.values])
