Mismatch when duplicating lua table - lua

Question

I'm writing a game using Lua and Love2d but I've hit a snag when dealing with nested tables.
I have a function that runs through a table containing numbers corresponding to walls, buttons, etc. and prints colored blocks based on the keys. An example of one of these tables would look like this:
map = {
{ 1, 1, 1, 1, 1, 1, 1, 1, 1 }
{ 1, 0, 0, 0, 0, 0, 0, 0, 1 }
{ 1, 0, 1, 1, 2, 0, 0, 0, 1 }
{ 1, 0, 0, 0, 0, 0, 0, 0, 1 }
{ 1, 1, 1, 1, 1, 1, 1, 1, 1 }
}
This works fine when rendered. However when I attempt to create this same table using a function that reads this data from a text file looking like this:
111111111
100000001
101120001
100000001
111111111
It creates a table that seems identical but it simply doesn't work when I try to render it.
So I tried debugging using a bit of code that prints out table contents and though the contents are the same, the bit of hex describing the nested tables are different. Example:
Reading the first nested table of the map file:
1 table: 0x106c5a720
1 1
2 1
3 1
4 1
5 1
6 1
7 1
8 1
9 1
Reading the first nested table of the manually created table:
1 table: 0x106c64120
1 1
2 1
3 1
4 1
5 1
6 1
7 1
8 1
9 1
What's going on here? The values are all identical but something strange is happening.
edit: Here's the bit of code that renders the map for reference:
for y=1, #map do
for x=1, #map[y] do
if map[y][x] == 1 then
print("found a wall")
love.graphics.rectangle("fill", x * 30, y * 30, 30, 30)
elseif map[y][x] == 2 then
print("found a button")
love.graphics.setColor(255, 0, 0)
love.graphics.rectangle("fill", x * 30, y * 30, 30, 30)
love.graphics.setColor(0, 0, 255)
end
end
end

When reading data from a text file, you are getting strings.
In your original map table you have numbers.
Numbers are not equal to strings.
assert(1 ~= '1')
