This lesson is part of Web Developer Tools · All levels

Summary

Group Lines arrange the row into several groups based on a particular number, pattern, or key. Clustering helps read long data, create reports per category, or set up batch processing. Ensure that the sequence and row content remain intact so that no data is lost when grouping.

Key points

Grouping can be based on a certain number of rows, keys, or patterns
Ten rows grouped per three yield four groups
The empty line can be used as a group separator
Key-based grouping is similar to GROUP BY in a database.
Maintain order and line integrity throughout the process
