How do i sort this type of table?? (table.sort not work)

I would restructure your tables into something a little more usable something like:

{
	Properties = {
		Looping = false,
		Priority = Enum.AnimationPriority.Core
	},
	Keyframes = {
		[1] = {
			["Time"] = 0,
			["HumanoidRootPart"] = {
				["Torso"] = {
				},
			},
		},
		[2] = {
			["Time"] = 0.5,
			["HumanoidRootPart"] = {
				["Torso"] = {
					CFrame = CFrame.new(0, 0, 60),
				},
			},
		},
		[3] = {
			["Time"] = 1.1,
			["HumanoidRootPart"] = {
				["Torso"] = {
					CFrame = CFrame.new(0, 0, 60) * CFrame.Angles(math.rad(112.472), 0, 0),
				},
			},
		},
		[4] = {
			["Time"] = 1.8,
			["HumanoidRootPart"] = {
				["Torso"] = {
					CFrame = CFrame.new(0, -151.054, -2.569) * CFrame.Angles(math.rad(112.472), 0, 0),
				},
			},
		},
		-- etc......
	}
}
-- this for loop is just to display what you have in your table!
for i=1, #Tab.Keyframes  do
	local Frame = Tab.Keyframes[i]
	print("==========================")
	table.foreach(Frame,function(a,b)
		print("[",i,"]",a," = ",b)
		if(typeof(b) == "table") then
			for j,n in pairs(b) do
				print("\t",j,n)
				if(typeof(n) == "table") then
					for t,g in pairs(n) do
						print("\t\t",t,g)
					end
				end
			end
		end
	end)
end

So now you can keep your frames in order but you would have something that reads the Time value so it keeps things synced.

The way you've got the table structure, it's making it hard to keep the keyframes in order as you've discovered.

When I'm working on something that needs frames i always keep the frames numbered easy like 1,2,3,4 etc... then have a separate part of your table reader reading the time stamp and displaying it at that time stamp making sure it gets played at the correct time.

Hope this helps! :)
