Seperate word thing

phrase = "lol so I want to make a algorithm that finds seperate words and puts them in a table which it seems simple enough to do"

local tab = {}
local lastnum = 0

for i=1,#phrase do
    if string.sub(phrase,i,i) == " " then
        table.insert(tab,string.sub(phrase,lastnum,i-1))
        lastnum = i+1
    end
end
table.insert(tab,string.sub(phrase,lastnum,#phrase))

for i=1,#tab do
    print(i,tab[i])
end
