Background color and Column min/max options in Spyder's DataFrame viewer are disabled

After pd.get_dummies I join newly created dataframe d_wm to my main df. But now I can't enable the option background colors when I want to see my main df in the variable explorer. This option and column min/max aren't available. Any solutions?

Example:

d_wm = pd.get_dummies(df["wmg"], prefix = 'wm_gr')

df = df.join(d_wm)

enter image description here

Solution

(Spyder maintainer here) Those options are disabled if the contents of your Dataframe are too large (too many rows, columns or data) to avoid lags when you're browsing it.
