Ui file: DT::dataTableOutput(paste0("siFactors_",i))

Server file: output[[paste0('siFactors_', i)]] <- DT::renderDataTable({ datatable(final_array, extensions='KeyTable', rownames = checkboxRows(final_array, checked = box_indices), options = list(deferRender = TRUE, paging = FALSE, searching = FALSE, autoWidth = FALSE, scrollX = TRUE, scrollY = 600, scrollCollapse = TRUE

                            )



              )
