Vim Table Mode
Dhruva Sagar sent in Vim Table Mode (GitHub: dhruvasagar / vim-table-mode, License: MIT), a plugin for automatically creating and formatting tables. A recent update adds support for calculations, allowing tables to behave like spreadsheets.
There's a demonstration video on YouTube that covers the basic features.
Move Until Char Changes
I coincidentally found a spreadsheet-inspired script called move_until_char_changes.vim by Joey Twiddle, which mimics the Ctrl-Arrow shortcut in Excel. This allows you to move until there's a new character under the cursor. It has various options:
let g:move_stay_in_column = 1 " Will not stop on shorter lines than the one we started on let g:move_skip_empty_lines = 1 " Never stop on an empty line (if also unifying, never stop on whitespace) let g:move_unify_whitespace = 1 " Tab, space and empty-line are all considered the same. let g:move_once_at_start = 1 " Don't stop on the very next line just because it has a different char from the current!
