In matplotlib 2.2 with python 2.7, the following code raises a KeyError. It succeeded in 1.5.3
Code for reproduction
import numpy as np
import matplotlib
import matplotlib.pyplot as plt
fig, ax = plt.subplots()
data = np.random.randn(10, 3)
rowLabels = list('abcdefghij')
colLabels = [0, 1, 2]
table = matplotlib.table.table(ax, cellText=data.T, rowLabels=colLabels,
colLabels=rowLabels)
fig.savefig('foo.png')Actual outcome
