You should be able to find your table (the matrix) in a variable named (sigma)DAT on the menu line. The (sigma) is the upercase sigma symbol and that's followed by the letters "DAT". It exists until you delete it, so you can edit it at will.
To add another column to a matrix use the COL+ command (see your manual for the syntax).
Before you append a column to the matrix you may do whatever math you want, like apply a function to each element, etc. Just convert it to a list with the AXL command. Then use the DOLIST or whatever operation you want. Finally, use the AXL again to convert it back to a column again and then COL+, as already mentioned.
If I recall correctly, the calc allows you to choose which columns to use in your plot. Or you can use the CSWP command to bring the columns that you want to use into columns 1 & 2; I think it uses those two columns by default.
I hope that gets you going.
