is it possible to add another number in the list next to the first number?

is it possible to add another number in the list next to the first number in the list like example 1 then you add a 4 next to it and it becomes 14 then add another example 5 so it becomes 145

example;

local MyList = {1,0,0}

and becomes like:

local MyList = {14,0,0}

then add another

local MyList = {145,0,0}

(I am new to Lua sorry)
