title: Creating a dataframe in pandas by multiplying two series together
body: <p>Say I have two series in pandas, series A and series B. How do I create a dataframe in which all of those values are multiplied together, i.e. with series A down the left hand side and series B along the top. Basically the same concept as this, where series A would be the yellow on the left and series B the yellow along the top, and all the values in between would be filled in by multiplication:</p>

  <p>Sorry, should probably have added that my two series are not the same length. I'm getting an error now that 'matrices are not aligned' so I assume that's the problem.</p>
