Dear Ed,
based on your reply, I understand that my initial reading of your question does not fit your needs. I wrongly assumed you wish to display in column C at either the result of column A, or of column B. But you want to display both values simultaneously in one column of recalculated values.
This is possible using an expression in the following pattern
str(if(vendor_1!=0,vendor_1,"NaN")) + str("; ") + str(if(vendor_2!=0,vendor_2,"NaN"))
The expression asks both columns independently for a value -- if there is no value, these if clauses will explicitly state the absence by issuing an «NaN» string. These results, regardless if a numeric result, or some text, will be converted into a string. These are separated by a third string comprising a semi-colon and an explicit space (but it could be any other separator character, too [.cvs files]). Eventually, the plus signs are used to concatenate the parts into the string displayed in the table.
Et voilà, in the sixth column (an example .dwar file is attached, too):
