My output is as follows:
As you can see, in Panel A, "All", "168", "162", and "6" are not aligned properly. Specifically, I would like "All" to be left aligned, while "168", "162", and "6" to be centered. Similarly in Panel B, I would like "All" to be left aligned while the numbers under the column "Quarters" to be centered. How can I do this using multirow?
multicolumn{1}{..}{...}
construction of cells?
