How to use table.sort()? And sort them by lowest value to highest?

[shlexr (jenson)]

I’m looking to sort my products by lowest robux to highest robux.

Current script

local frCashProducts = {

	["10 frCash"] = {

		[1] = "10 frCash", -- Name
		[2] = 49, -- Price in robux
		[3] = 1110641683, -- Product ID

	};
	["50 frCash"] = {

		[1] = "50 frCash", -- Name
		[2] = 249, -- Price in robux
		[3] = 1110785170, -- Product ID

	};
	["100 frCash"] = {

		[1] = "100 frCash", -- Name
		[2] = 349, -- Price in robux
		[3] = 1110785246, -- Product ID

	};
	["250 frCash"] = {

		[1] = "250 frCash", -- Name
		[2] = 799, -- Price in robux
		[3] = 1110785314, -- Product ID

	};
	["500 frCash"] = {

		[1] = "500 frCash", -- Name
		[2] = 1499, -- Price in robux
		[3] = 1110785395, -- Product ID

	};
	["750 frCash"] = {

		[1] = "750 frCash", -- Name
		[2] = 2499, -- Price in robux
		[3] = 1110785496, -- Product ID

	};
	["1000 frCash"] = {

		[1] = "1000 frCash", -- Name
		[2] = 3499, -- Price in robux
		[3] = 1110785596, -- Product ID

	};

}


local sortedTable = table.sort(frCashProducts,
	function(a,b)
		return a[2] < b[2]
	end
)

for i,v in pairs(sortedTable) do
	print(v[1].." | "..v[2]) -- Checks the table is done correctly
end

This doesn’t seem to work and just says table expected but nil is found when printing.

Solution 2 spairs

Credit to this StackOverflow post

Here’s a modified version of pairs- called spairs
(This is in a modulescript)

return function (t, order)
    -- collect the keys
    local keys = {}
    for k in pairs(t) do keys[#keys+1] = k end

    -- if order function given, sort by it by passing the table and keys a, b,
    -- otherwise just sort the keys 
    if order then
        table.sort(keys, function(a,b) return order(t, a, b) end)
    else
        table.sort(keys)
    end

    -- return the iterator function
    local i = 0
    return function()
        i = i + 1
        if keys[i] then
            return keys[i], t[keys[i]]
        end
    end
end

Here’s an example use:

local spairs = require(script.spairs)

local plrs = {}
plrs['coolboy123'] = 216
plrs['funfungamers'] = 683
plrs['asdasdasd'] = 120

local function order(t, a, b)
	return t[b] < t[a]
end

for i,v in spairs(plrs, order) do
	print(i, v)
end

Our output is as expected.

funfungamers 683
coolboy123 216
asdasdasd 120
