I'm looking for either some built-in setting or a simple mode for viewing and editing tab-separated columns (TSV files).
All I need is for the TSV text to be displayed in a way that respects the vertical alignment of the columns, and the horizontal alignment of the rows. If line-wrapping could be toggled that would be sweet, but secondary.
Searching for column viewing in emacs is made difficult by the fact that the word "column" already has a different meaning in Emacs.
(I specified "simple" to discourage answers like org-mode's column view. At the moment my needs are extremely simple, and I don't want to contend with installing, loading, and learning about a monster mode like org.)
