Bug summary

Specifying fontsize kwarg in matplotlib.pyplot.table doesn't have any effect.

Code for reproduction

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)
y = x + 1
tableData = [['a', 1], ['b', 1]]

fig, ax = plt.subplots()
ax.plot(x, y)
t = ax.table(
    cellText=tableData,
    loc='top',
    cellLoc='center',
    fontsize=30
)
plt.show()

Actual outcome

Expected outcome

A table with bigger font size.

Additional information

This works:

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 10, 100)
y = x + 1
tableData = [['a', 1], ['b', 1]]

fig, ax = plt.subplots()
ax.plot(x, y)
t = ax.table(
    cellText=tableData,
    loc='top',
    cellLoc='center'
)
t.set_fontsize(30)  # <----------------
plt.show()
