this is the source commt #5590 i try to add PaimonDataSourceV2RelationTableExtractor in TableExtractor to make we can fix the question, but when i add the extractor and get table info, this is the root call extrcator code

case class RuleApplyRowFilter(spark: SparkSession) extends RuleHelper {

  override def apply(plan: LogicalPlan): LogicalPlan = {
    val newPlan = mapChildren(plan) {
      case p: RowFilterMarker => p
      case scan if isKnownScan(scan) && scan.resolved =>
        val tables = getScanSpec(scan).tables(scan, spark)
        tables.headOption.map(applyFilter(scan, _)).getOrElse(scan)
      case other => apply(other)
    }
    newPlan
  }

  private def applyFilter(
      plan: LogicalPlan,
      table: Table): LogicalPlan = {
    val are = AccessResource(ObjectType.TABLE, table.database.orNull, table.table, null)
    val art = AccessRequest(are, ugi, QUERY, AccessType.SELECT)
    val filterExpr = SparkRangerAdminPlugin.getFilterExpr(art).map(parse)
    val filtered = filterExpr.foldLeft(plan)((p, expr) => Filter(expr, RowFilterMarker(p)))
    filtered
  }
}

if we add two exector for the RelationV2 plan, we will get two tables, but the apply code only use the first table if the tables is

Table(Some(paimon_catalog),None,table1,Some(admin))
Table(Some(paimon_catalog),Some(paimon_ns),table1,Some(admin))

the source code will only filter the first table result, is that right?
