Word frequencies

Hi, I'm not a programmer. rather, I'm a linguist and I'm hoping SuperEdi will help me do this: I want to take word frequency lists from multiple documents and merge them into a single table.

For example

DOC1
the 34
me 2
park 7

DOC 2
the 45
us 8
park 9
walk 17

OUTPUT =

WORD DOC1 DOC2
the 34 45
me 2 0
park 7 9
us 0 8
walk 0 17
