Allow pasting tables

tablepaste.js

// Some focusable element can be rigged to accept user paste events
// Then the HTML is taken from it, which should have a table element if what they copied is a table
focusableElement.onpaste = e => {
  const data = e.clipboardData.getData('text/html')

  const dom = document.createElement('div')
  dom.innerHTML = data

  const table = dom.querySelector('table')
  const rows = [...table.rows].map(tr => (
    [...tr.querySelectorAll('td')].map(td => td.textContent)
  ))

  console.log(rows) // string[][]

  outputElement.textContent = JSON.stringify(rows, null, 2)
}
