nft list table filter
table ip filter {
        chain input {
                type filter hook input priority 0; policy accept;
                flow table __ft0 { ip saddr counter packets 0 bytes 0}
                flow table __ft1 { ip daddr counter packets 0 bytes 0}
        }

... so the internal name will be shown.
