TCPDF Cell Position

I just wanted to add that if on line 80 I add:

$pos = 1; //I get all 3 cells on separate lines, as expected

echo 'pos= ' . $pos; //I get pos= 0pos= 0pos= 1, also as expected

so...why doesn't my cell 3 does not fall under next line?

Is this what you're trying to get?

Hi Ray,

Your code does produce what I need, but my question is what is wrong with my code above?

Honestly, I don't know what is wrong, and this answer is not intended to be flippant.  I don't look at code that does not work if I can avoid it.  I've written enough unworking code that I'm more interested in getting something to work, and reading unworking code is usually not the fast way to a solution.  When you start with a clean slate you can build the solution one step at a time, with automated testing along the way.  When you start with unworking code, you don't know how to write the automated tests because you don't know what the code should do - you just know that it doesn't work.  So I never read code samples, except to scan for obvious code smells, preferring instead to concentrate on the inputs and desired outputs.  Your description of the expected outputs was clear enough to me, so I just put together a sample that seemed to get a good outcome.
