Naming Column Headers

Because every block has defined number of rows and Subsets make it easy to organize your data, it makes more sense than ever to name your columns. To name a column, you can press the dropdown at the top of each column and click “rename.”
Once you have a column named, you can call upon the column in formulas and dynamic block references.
In the example above, Grid 1 is creating dynamic rows based off of the Name of column A in the Data block.
