Editing markdown tables can be a drag. mdtt makes it easier with a slick TUI for terminal use and vim-style keybindings. It supports output to stdout and in-place file editing.

To install mdtt using Go, run:

go install github.com/szktkfm/mdtt/cmd/mdtt@latest

Or, download it:

GitHub Releases

To start editing your markdown table, simply run:

mdtt filename.md

Upon launching, mdtt will display the tables from your markdown file in a TUI.

While editing, you can utilize the following vim-like keybindings to navigate and modify your tables efficiently:

• Navigation: Use hjkl for left, down, up, and right movements.
• Editing: Press i to switch to insert mode and edit cell content, exit insert mode with esc or ctrl+c.
• Row and Column Manipulation:
  • Add a new row or colymn with o, vo.
  • Delete the current row or column with dd, vd.
  • Copy the current row or column with yy, vy.
  • Paste a copied row or column with p.

For direct editing and saving changes to the same file, use:

mdtt -i filename.md

You can use piping with mdtt as shown below:

pbpaste | mdtt | pbcopy

To create a new table without an existing file, run mdtt without any arguments:

mdtt

When multiple tables are present, you will be prompted to select the table you wish to edit.

Press I to open the cell in the text editor set as your $EDITOR, allowing you to edit the cell directly within your chosen editor.

• Vim-like Keybindings: Navigate and edit tables using familiar vim commands.
• Inplace Editing: Directly modify your original markdown files with the -i option.
• Piping Support
• Multi-Table Selection
• External Editor Integration: Delegate cell editing to an external editor specified by your $EDITOR environment variable.
• HTML in Cells: Enable rich content formatting by using HTML directly within table cells.

This project, mdtt, was inspired by mdvtbl, a tool that reads markdown from stdin, allows for table editing in a web view, and outputs to stdout.
