Stream result rows

[ns-cweber]

Because we're printing into a table whose column widths are determined by the widest value in the column, the entire table must be loaded before the first row can be printed. This means the user has to wait a long time to read rows that the program is otherwise ready to display. We should find a print format that is suitable for streaming; either fixed-width columns with word-wrapping/truncation or we should print a "row" as a key/value paragraph:
