Fix Python – Seaborn showing scientific notation in heatmap for 3-digit numbers

I’m creating a heatmap from a pandas pivot_table as below:
table2 = pd.pivot_table(df,values=’control’,columns=’Year’,index=’Region’,aggfunc=np.sum)

I looked through the examples in Matplotlib and they all seem to already start with heatmap cell values to generate the image.
Is there a method that converts a bunch of x, y, all different, to a heatmap (where zones….
