boxtable.nvim

Unicode box-drawing tables you can edit in place. Convert pipe/tab rows into a table, then move between cells, add/remove rows and columns, and type into cells — the table re-renders (with word-wrapped cells and a centered header row) whenever you leave insert mode.

Install

lazy.nvim:

{ "booka66/boxtable.nvim", opts = {} }

Usage

• :BoxTable — insert an empty 2×2 table at the cursor.
• :'<,'>BoxTable — convert selected lines. Accepts | a | b |, a | b, tab-separated, or an existing box table (reflows it). Markdown |---| rows are ignored. First row is the header.
• :'<,'>BoxTable 60 — override the total table width for this call.

Whenever the cursor is inside a table, editing keymaps are active (buffer-local):

Key	Action
<Tab>	next cell, cursor at end of its text (past the last cell adds a row) — normal + insert; from insert mode you stay in insert
<S-Tab>	previous cell — normal + insert
<leader>th/j/k/l	move to cell left/down/up/right
<leader>to / <leader>tO	add row below / above
<leader>tc / <leader>tC	add column right / left
<leader>td / <leader>tD	delete row / column

Just type into a cell; on InsertLeave (or any normal-mode change) the table is re-rendered and the cursor stays in the same cell. Don't press <CR> inside a cell — use <leader>to for a new row. To make the first row a header, <leader>tO on row 1.

:BoxTableMode toggles the keymaps manually (use with auto_mode = false).

Options

require("boxtable").setup({
  width = 90,       -- target total table width; the widest columns wrap to fit
  pad = 1,          -- spaces on each side of cell contents
  auto_mode = true, -- enable keymaps when the cursor is inside a table
  keymaps = {       -- set any to "" to disable
    next_cell = "<Tab>", prev_cell = "<S-Tab>",
    cell_left = "<leader>th", cell_down = "<leader>tj", cell_up = "<leader>tk", cell_right = "<leader>tl",
    row_below = "<leader>to", row_above = "<leader>tO",
    col_right = "<leader>tc", col_left = "<leader>tC",
    delete_row = "<leader>td", delete_col = "<leader>tD",
  },
})

All actions are also exposed as functions (require("boxtable").row_below() etc.) for custom mappings.
