Updating the DataTable tab without having to reopen the DataTable file

[Zeek_Feed]

Hello, I have a manager class that updates and fill information in a DataTable. Also in this class there are 2 buttons “update” and “clear”. Everything works, but when I update/clear the data, I have to reopen the DataTable from the Content Browser. Is there any solution how to update the information without doing this?

void AGameManager::RefreshData()
{
    StationsTable = LoadObject<UDataTable>(nullptr, *TablePath);

    TSharedPtr<FJsonObject> a;

    FString Path = FPaths::ProjectDir() + "Source/stations.json";  
    LoadAndFillDataTable(StationsTable, Path);

    StationsTable->HandleDataTableChanged();
    // <-- update tab here
}

void AGameManager::ClearData()
{
    StationsTable->EmptyTable();
    // <-- and here
}

In the screenshot below I have already updated the DataTable but it does not appear in the window on the right. I have to reopen the DataTable every time
