Let's have a look at the Data Table step we added last time. Double-clicking will reveal the details:
Next comes the name of the step. I recommend to add a little bit more detail to the name so you can uniquely identify each step. And next comes the description field. You can write a detailed description of what the step does. The format to be used is Markdown and you have many possibilities to format the text, add lists, links, images, diagrams and much more. In the upper right hand corner of the description field you can click on the icon to choose how the markdown text should be presented to you: just the editor, with a preview or only the preview. Look here for more details on the Markdown syntax. Once you have added the description and go back to the canvas, the step will have a yellow marker and you can hover over it to display the description.
Note that the "date_of_birth" column in this example is of type "datetime". If you right-click the column, and hover over "Morph To", you get a menu displayed with various data types. This is how you can change the type to e.g. a string, number, list, dict or something else. You can also select the field to be of type "formular" where you can add formulas or functions according to the Tweakflow expression language.
The last section to edit are the "Output Fields". Here you can select which details to output. There is a "results" object available and you can use the syntax shown to output the individual fields of each row. The individual rows are actually dictionaries and you can pass the name of the field to get its value:
Next time we look at some more features of the UI and we will have a deeper look at some of the functions that are available.
