There's no row number output for userlists. You can use CSS to add it though using a counter. Example as follows.
Code:
.cbUserListLayoutList .cbUserListRow {
counter-increment: rowNumber;
}
.cbUserListLayoutList .cbUserListRowCol1:before {
content: counter( rowNumber );
}
That would insert the row number into the first column of the userlist for example. Main issue is page 2 would start off at 1 again.
