Table Formatter

An Obsidian plugin for formatting Markdown tables on save.

Features

• Formats Markdown tables whenever a Markdown file is saved.
• Runs auto-format while editing in Live Preview or Source mode (never in Reading view).
• Waits for a pause in typing (3 seconds by default, configurable) before auto-formatting, so it does not interfere with ongoing edits. Because the wait restarts on every change, the formatter also runs after edits Obsidian itself makes to the file, such as re-padding a table edited through the Live Preview table editor.
• Applies edits through the open editor, so the cursor stays in place and Obsidian does not report the file as externally modified.
• Leaves the table the cursor is in untouched during auto-format and reformats it once the cursor has moved out of it, so cell editing is never interrupted. The manual command always formats everything.
• Lets you format manually with the ribbon button (table icon) or the command palette.
• Can format every Markdown file in the vault at once with the command "Format tables in all files", which is handy when you first add the plugin to an existing vault. It asks for confirmation first and reports how many files were changed.
• Adds a ribbon toggle button (power icon) to force-enable/disable auto-format and focus control while editing.
• Shows an ON/OFF toggle in the main screen status bar for quick switching.
• Supports configurable table cell padding:
  • Fixed number of spaces (0 or more)
  • Blank (auto mode: single-space minimal formatting)
• Supports configurable number of - characters in the delimiter row.
• Keeps column alignment: the : markers in the delimiter row (:---, ---:, :---:) are preserved.

Settings

Open: Settings -> Community plugins -> Table Formatter

• Padding spaces
  • Blank: | cell | style (single-space padding)
  • Integer (>= 0): exactly that many spaces around each cell
• Table border dash count
  • Blank: auto (based on content width, minimum 3)
  • Integer (>= 1): fixed number of - in each delimiter cell. Alignment colons (:) are kept and placed around the dashes, so a left-aligned column with dash count 3 becomes :---.
• Auto-format delay
  • Seconds to wait after the last change before tables are auto-formatted (integer >= 1, default 3)
• Enable auto-format and focus control while editing
  • ON: run modify-triggered formatting while editing in Live Preview or Source mode
  • OFF: force-disable those editing features
• Table indentation formatting
  • Preserve table indentation: indented tables are excluded from formatting
  • Remove table indentation: indented tables are formatted and indentation is removed
• Empty cell formatting
  • Padded, "| |": unchanged, | |
  • Single space, "| |": | |, which MD060 compact accepts

Community Plugin Release

Use one of the following version bump scripts depending on the scope of changes:

• npm run version:patch
  • For backward-compatible fixes only (x.y.z -> x.y.(z+1))
• npm run version:minor
  • For backward-compatible feature additions (x.y.z -> x.(y+1).0)
• npm run version:major
  • For breaking changes (x.y.z -> (x+1).0.0)

Each script updates package.json, package-lock.json, manifest.json, and versions.json together.

1. Commit and push to GitHub.
2. Create a GitHub Release with tag exactly matching manifest.json version.
3. Attach release assets: main.js, manifest.json, styles.css (optional).
4. Submit the repository URL from Obsidian Community Plugins.

Notes:

• manifest.json in the default branch must be up to date before submission.
• versions.json should stay in the repository root for Community Plugin compatibility mapping, but it does not need to be attached to the GitHub Release.
• Plugin id must be unique and must not contain obsidian.
