Pulls arbitrary table data out into a TSV

tableizer.js

trs = document.querySelectorAll('tr');
Array.prototype.map.call(trs, function(tr) {
  if(tr.children.length > 2) {
    return Array.prototype.map.call(tr.children, function(td) {
      return td.textContent.trim();
    }).join("\t");
  } else { 
    return null;
  }
}).join("\n");

// As one line
Array.prototype.map.call(document.querySelectorAll('tr'), function(tr) { if(tr.children.length > 2) { return Array.prototype.map.call(tr.children, function(td) { return td.textContent.trim(); }).join("\t")} else { return null; } }).join("\n");
