How to sort table by key

[maffius]

How can I use table.sort to sort table "lista" in my script? I want to sort players in gridlist by their name.

 

function aktualizujKontakty()
    lista={}
    for i,v in ipairs(getElementsByType("player")) do
        if v~=localPlayer then
            lista[getPlayerName(v)]={v,getElementData(localPlayer,"PW:"..getPlayerName(v)) or ""}
        end
    end
end

function wyswietlKontakty()
    guiGridListClear(gridlist[1])
    for i,v in pairs(lista) do
        r=guiGridListAddRow(gridlist[1])
        guiGridListSetItemText(gridlist[1],r,1,skipColorCode(i),false,false)
        guiGridListSetItemData(gridlist[1],r,1,i)
        if nieodczytane[i] then
            guiGridListSetItemColor(gridlist[1],r,1,0,255,0)
        end
        if zablokowany[i] then
            guiGridListSetItemColor(gridlist[1],r,1,255,0,0)
        end
    end
end

function pairsByKeys (t, f)

	for n in pairs(t) do table.insert(a, n) end
		table.sort(a, f)
		local i = 0      -- iterator variable
		local iter = function ()   -- iterator function
		i = i + 1
		if a[i] == nil then return nil
			else return a[i], t[a[i]]
		end
	end
return iter
end

function wyswietlKontakty()
    guiGridListClear(gridlist[1])
    for i,v in pairsByKeys(lista) do -- see this line 
        r=guiGridListAddRow(gridlist[1])
        guiGridListSetItemText(gridlist[1],r,1,skipColorCode(i),false,false)
        guiGridListSetItemData(gridlist[1],r,1,i)

    end
end

This will sort table by key and will add players automatically

Works good, but it sorts wrong because when someone has nick "test" and few other players have nicks with first upper case then "test" will be last in the list

Nevermind i fixed it by myself  Topic can be closed
