lua split into words

I have a string in lua.

It's a bunch of [a-zA-Z0-9]+ separated by a number (1 or more) spaces.

How do I take the string and split it into a table of strings?

Here is an example how to split words and merge them:

function mergeStr (strA, strB)
  local tablA, tablB = {}, {}
  for word in strA:gmatch("%S+") do
    table.insert (tablA, word)
  end
  for word in strB:gmatch("%S+") do
    table.insert (tablB, word)
  end
  return tablA[1] .. ' ' .. tablB[3] .. ' ' .. tablA[5]
end

print (mergeStr ("Lua is a programming language", "I love coding"))
-- "Lua coding language"

s = "foo bar 123"
words = {}
for word in s:gmatch("%w+") do table.insert(words, word) end
