Multi-line function tables in lua

I cannot find any other online help for creating a table containing multi-line functions. For example, here's a snippet of code from the wiki wiki.

action = {
  [1] = function (x) print(1) end,
  [2] = function (x) z = 5 end,
  ["nop"] = function (x) print(math.random()) end,
  ["my name"] = function (x) print("fred") end,
}

      

        
        
        
      

    

I want to do something like this:

action = {
[1] = function blah()
more code here
end

[2] = function blahblah()
more code here
end

}

      

        
        
        
      

    

So how can I do this?
