Select multiple non-contiguous rows

[dbdante]

I am trying to see if I could select multiple non-contiguous rows. SmartTable internally uses TableRow which has multiline selection. I am not sure if this works only when the rows are continuous. The aim is to essentially give the user an option to ctrl+click to select non contiguous rows. I am not able to use set_selection to achieve this. I would appreciate any insights in going about implementing it.
