Are you trying to build something like a table? Why don’t you try using a Data Grid. It could be even easier to handle :).
About your question, try playing a bit with the styling (Appearance) of your “List View”. Here you can change the Style to “No Styling” to get rid of paddings and borders or even change the “Row Size”. After that, you could add some css (padding, margin, borders) the generated table or to the cells.
