Why does the TableSymbol from the ResultType always lack the Name property?

[FaresKi]

Hi! I'm struggling with an issue here. I have a query composed of statements, and various expressions, including PipeExpressions.

let variable = TableName
    | where TimeGenerated > ago(check_period)
    | where ColumnA == "Value"
    | where ColumnB in ("A", "B")
    | where ColumnC == "Value_bis";
...

I want to extract the table from this query (TableName here) and store it in my list:

public static List<string> GetTables(KustoCode code)
        {
            var tables = new List<string>();
            GatherTables(code.Syntax);
            return tables;

            void GatherTables(SyntaxNode root)
            {
                SyntaxElement.WalkNodes(root,
                    fnBefore: n =>
                    {
                        if (n.ReferencedSymbol is TableSymbol t
                            // && code.Globals.IsDatabaseTable(t)
                            )
                        {
                            tables.Add(t.Name);
                        }
                        else if (n is Expression e
                            && e.ResultType is TableSymbol ts
                            //&& code.Globals.IsDatabaseTable(ts)
                            )
                        {
                            tables.Add(ts.Name);
                        }
                        else if (n.GetCalledFunctionBody() is SyntaxNode body)
                        {
                            GatherTables(body);
                        }
                    },
                fnDescend: n =>
                    // skip descending into function declarations since their bodies will be examined by the code above
                    !(n is FunctionDeclaration)
                );
            }
        }

As you can see I've inspired myself from the readme but changed the return type. What I've noticed while debugging is that despite the Parser recognizing it's a TableSymbol, it will provide an empty ("") value for the Name or AlternateName. Am I missing something? Same issue if I provide a schema thru the Globals. TIA

The parser uses the TableSymbol to both represent the named tables in a database and the result of each tabular operation. All tabular operators return a different TableSymbol than they started with, never with a name, since they represent intermediate states.
