Alternating rows background - updating dynamically when hiding/showing rows with css only?

Question

I have a table ".report" and it should have alternating background for its rows. The UI allows users to hide and show rows dynamically and I want the background of the rows to keep the pattern at all times. I implemented the solution where I add the ".hidden" class to the hidden rows and set the background-color attr to shown rows only and then set the background to "nth-of-type" accordingly. But it doesn't work. It seen the nth-of-type doesn't take the ":not(.hidden)" rule into consideration. Is it possible to resolve this with CSS only? I know I can change the background with JS but I'd rather avoid it and use css only if possible.

restoreRow: function(key) {
    let row = $("#" + key);
    row.show();
    row.removeClass("hidden");
},

removeRow: function(key) {
    let row = $("#" + key)
    row.hide();
    row.addClass("hidden");
},

.report tbody tr:not(.hidden):nth-of-type(even) {
    background-color: $white;
}

.report tbody tr:not(.hidden):nth-of-type(odd) {
    background-color: red;
}

Answer 1

Yes, with the new nth-child(n-of-x) selector

tr:nth-child(odd of :not(.hidden)) {
  background: lightgreen;
}

tr:nth-child(even of :not(.hidden)) {
  background: lightblue;
}

table {
  border: 1px solid grey;
  margin-bottom: 2em;
}
td {
  border: 1px solid red;
}

.hidden {
  display: none;
}

tr:nth-child(odd of :not(.hidden)) {
  background: lightgreen;
}

tr:nth-child(even of :not(.hidden)) {
  background: lightblue;
}
