How do I create my own table manually? I want to create a 3x2 table which I can join with a large dataset. How do I do this without going back to excel and making it and importing it?
Yes, that is one option. The other one is to use the Data Editor view which you can bring up via the menu View -> Show Panel -> Data Editor. With this you can edit existing example sets in your repository and store them again. But you can also start with an empty one and add columns and rows easily.
You can specify your table by using Create ExampleSet operator and then use Join or Append operator to join this table to your existing dataset.
Hope this helps,
