How do you store a CFrame value in a table?

I'm experimenting with CFrame and tried storing a CFrame value to a table. I had struggles with it. How do you do it?

Here's my code and please answer with details. My code is some kind of detection. I think detection of which if a part went out of a certain area it will turn red, otherwise green.

BrickMode = true -- Just some kind of mode to find it using parts. I need to make invisible points without depending on bricks. Just CFrame points.









model = nil
axis = 1
neg = 0
if BrickMode == true then
    if workspace:FindFirstChild('SurfaceDetectionPoints') then
    model = workspace.SurfaceDetectionPoints
    else
        Instance.new("Model",workspace).Name = 'SurfaceDetectionPoints'
        model = workspace.SurfaceDetectionPoints
    end
    for o = 1,6 do
        newIns = Instance.new("Part",model)
        newIns.Color = Color3.new(0,1,0)
        newIns.Anchored = true
        newIns.Size = Vector3.new(0.2,0.2,0.2)
        newIns.Material = "Neon"
        newIns.CanCollide = false
        newIns.Name = "SURFACEDETECTIONPART"
    end
end
-- Creates an instance for keeping the parts
while true do

    size = script.Parent.Size
    points = {
        script.Parent.Size.Z / 2,
        script.Parent.Size.Z / 2,
        script.Parent.Size.X / 2,
        script.Parent.Size.X / 2,
        script.Parent.Size.Y / 2,
        script.Parent.Size.Y / 2
    }
    -- Above are points for simple surface detection.


    if BrickMode == true then
        newPart = model:GetChildren()
    end
    for i = 1,#points do
        invisPoints = {}
        -- setting
        cAxis = nil
        if axis == 1 then
            if neg == 0 then
                cAxis = Vector3.new(0,0,points[i])
            else
                cAxis = Vector3.new(0,0,-points[i])
            end
        elseif axis == 2 then
            if neg == 0 then
                cAxis = Vector3.new(points[i],0,0)
            else
                cAxis = Vector3.new(-points[i],0,0)
            end
        elseif axis == 3 then
            if neg == 0 then
                cAxis = Vector3.new(0,points[i],0)
            else
                cAxis = Vector3.new(0,-points[i],0)
            end

        end
