By changing the header to "With speedup (ms)" and "Without speedup (ms)", the documentation will directly highlight the performance improvements. This makes it easier for users to understand the value of these libraries without needing to know about older versions.

.. csv-table::
    :header: "Operation", "With speedup (ms)", "Without speedup (ms)", "Ratio"
    :widths: 25, 25, 25, 25

    ``df1 > df2``, 13.32, 125.35,  0.1063
    ``df1 * df2``, 21.71,  36.63,  0.5928
    ``df1 + df2``, 22.04,  36.50,  0.6039
