Table
=====

Basic example with a confusion matrix:

.. code-block:: python

    import matplotlib.pyplot as plt

    cellText = [
        ["True Positive\n3740", "False Negative\n743"],
        ["False Positive\n190", "True Negative\n6723"],
    ]
    cellColours = [
        ["green", "red"],
        ["orange", "green"],
    ]

    fig = plt.figure(figsize=(6, 3), tight_layout=True)
    ax1 = fig.add_subplot(111)
    ax1.set_axis_off()
    table = ax1.table( 
        cellText=cellText,
        rowLabels=["Acual\nPositive", "Acual\nNegative"],
        colLabels=["Prediction\nPositive", "Prediction\nNegative"],
        cellLoc="center", # The alignment of the text within the cells.
        rowLoc="center", # The text alignment of the row header cells.
        colLoc="center", # The text alignment of the column header cells.
        colWidths = [0.4, 0.4],
        cellColours=cellColours,
        rowColours=["#DFFCFF", "#DFFCFF"],
        colColours=[(0.875, 0.99, 1), (0.875, 0.99, 1)],
        loc='center right'
    )
    table.set_fontsize(34)
    table.scale(1, 4)
    # Set the height of the header cells
    cellDict = table.get_celld()
    for i in range(0, 2):
        cellDict[(0, i)].set_height(.2)
    # Set the opacity of the cells
    for cell in table._cells:
        table._cells[cell].set_alpha(.6)
    ax1.set_title("Confusion Matrix")
    fig.savefig("table.png", bbox_inches='tight')
    plt.close(fig)
