A Markdown table breaks quietly. A row with one cell too many silently loses a value in GFM; a row with one too few silently gains an empty one. A pipe typed inside a code span splits the row even though it looks like content. A delimiter row with one wrong character turns the whole block back into a paragraph. None of this is reported by the renderer, and a reviewer reading the diff sees pipes that line up.
This walkthrough uses the tool's public README and checked-in example files. Run the command from a repository checkout with Node.js 22+; inspect the source before using it on your own files.
Run the checked-in example
npm install github:edilec/markdown-table-validatorRead the result
This installs the public GitHub source; markdown-table-validator is not published to npm.
Where this check stops
It also does not fix anything. The preview is a separate file you can read, diff and copy from; nothing is written back over your documents.
Before adapting the command to your own workflow, review the accepted inputs, exit codes and safety boundaries in the README.
