Row editors are tools used for editing a row in a grid.
Grids are often used for displaying records from a database. One row in such grid corresponds to one record. Row editors are tools used for editing one row at a time.
An alternative to a row editor is a form, which can be used to edit more complex records.
For simpler records, a row editor has an advantage that a user can see surrounding rows with stored values while editing a row.
