I have a table:

Table I want to be editable

I want it to be editable only where the zeros appear. I read this post Generating an editable table that can be used as input because it's almost exactly what I want, but I couln't figure out how to keep uneditable the first column AND the first row. I don't show the modifications I did because they wouldn't shed any light.

I'll show you hoe to do it for a 3 x 3 matrix of values. You should be able to extend to 3 x 12 without much trouble

First do some initialization.

headers = {"Jan", "Feb", "Mar"};
rowLbls = {" ", "Tmax", "Tmed", "Tmin"};
valTbl = ConstantArray[0, {3, 3}];

Next build the spreadsheet.

      Array[InputField[Dynamic@valTbl[[#1, #2]], Number, FieldSize -> Tiny] &, {3, 3}],
  }] // TableForm


Finally a place to view the changes to valTbl as they occur.

Dynamic @ valTbl
{{0, 0, 0}, {0, 42, 0}, {0, 0, 0}}

That's what I was looking for. Thanks! – Mantizaurio Jun 13 '14 at 0:27
