+This markdown table is badly messed up:
+

+| tex_packages.md           | tex|

+| format_md.md           | vim|
+
+```
+
+Highight from the top with `V6j`, then run `column` to fix the output:
+
+```vim
+:!column -ts'|' -o '|'
+```
+
+It displays like this:
+
+```vim
+:'<,'>!column -ts'|' -o '|'
+```
+
+```markdown

+
+
+That's better, but the header is broken.
+Fix is by replacing spaces with dashes.
+
+```vim
+:s/ /-/g
+```
+
+The lines have too much whitespace.
+You can fix this with the 'truncate' command, to squeeze repeating spaces or dashes.
