I want to have equations in a column of a table, using the amsmath cases option, but where the column is left aligned. The MWE below shows an example of the equations that I need in the column, with the second table showing the layout I am after.

What I found online suggests you need the p{} option in order to include the cases option from amsmath. The array package has been suggested as a way to get the left aligned in the second column, but I cannot get it working as I expected it to.

Appreciate any pointers to what I am doing wrong.
