The problem is that the Smarty variable calls({$SKU}, or {$data.SKU}, or
whatever is the propper Smarty syntax) from {cell}..{/cell} are not working..
These {cell} tags are parsed only one time, and we can not put new values in
them each time we need a new row parsed. These {cell} tags are parsed even
before the first smarty_block_list() call - check the compiled version of
the template for proof.

How Smarty works (correct me if I am wrong about something) - first it
analyzes the template (smarty syntax), then it creates the compiled version
of the template (php script in the smarty_compiled folder), then this
compiled version is included and run. Running the included compiled version
triggers the block functions that are declared in them.

When we use {section} or {foreach} (which are core Smarty plugins), Smarty
adds special code in the compiled versions, which handle the access to data
for each iteration loop. That's what we lack when we do our {row} block tag..
