<div dir="ltr">Hi,<div><br></div><div>Without having thought it through that much or having understood the whole context:</div><div><br></div><div>1. Can't you just replace each ' in your Lua text by '' (two single quotes) before compiling the Smalltalk method string? It escapes the single quotes in the string.</div><div>2. Do you really need to create a new Smalltalk class for each row? (That feels weird to me.) Why not create an instance of something for each row and store the collection of all the instances in a well-known place?
