How to create a custom DataTable node?

Development Programming & Scripting

Hi everyone, I am trying to implement this in my project but since I am not a programmer but a designer I don’t really know what am I failing at. My goal is to create the same custom node this user is creating:

DataTableRowHandle to Get Data table row: Only literal data table is supported

But I am completely lost. My code looks like this:

.h

#include "CoreMinimal.h"
#include "Kismet/BlueprintFunctionLibrary.h"
#include "DTFunctionLibrary.generated.h"

/**
 * 
 */
UCLASS()
class TESTCPLUSPLUS_API UDTFunctionLibrary : public UBlueprintFunctionLibrary
{
	GENERATED_BODY()
		UFUNCTION(BlueprintCallable, Category = "DataTable")
		static FCinematicDataTable GetRowByName(UDataTable* dataTable, FName pName, bool& result);
	
};

.cpp

#include "DTFunctionLibrary.h"

FCinematicDataTable UDTFunctionLibrary::GetRowByName(FCinematicDataTable* dataTable, FName pName, bool& result)
{
	result = true;
	FCinematicDataTable* data = dataTable->FindRow<FCinematicDataTable>(pName, "", false);
	if (data == NULL)
	{
		result = false;
		return FCinematicDataTable();
	}
	return *data;
}

Just like his, but for some reason I can’t get it done. This is probably something easy for a C++ programmer but for a designer like me it’s horrible, so even if its a little bit ridicule to ask for help like this, I would really appreciate if you showed me the way. Thanks in advance.
