I dont know exactly what you mean; but if the question is:
if you use this.renderChunk to render columns in a cmp can you use other cells in the renderChunk?
The answer is yes. If you have 2 columns; i.e. "productname" and "productnr" you can use this.renderChunk and fill in something like
[[+productname]] has number [[+productnr]]
the column wil then display:
Boxproduct has number 0001
This that what you are after?
