Editing CSV and Similar Files in Table Format
This feature is supported in the ULtimate edition only
Overview
For text files containing delimiter-separated value(e.g. CSV, TSV), IntelliJ IDEA provides an alternative, table editor. (See Opening the table editor.)
Most of the functions in the table editor are accessed as context menu commands. Many of the commands have keyboard shortcuts.
Note that the context menus for the header row and the rest of the table are different.
