Answer 1

I used the previous answers and combine them to create:

Search any columns by hide rows and highlighting

Css for highlight found texts:

em {
   background-color: yellow
}

Js:

function removeHighlighting(highlightedElements) {
   highlightedElements.each(function() {
      var element = $(this);
      element.replaceWith(element.html());
   })
}

function addHighlighting(element, textToHighlight) {
   var text = element.text();
   var highlightedText = '' + textToHighlight + '';
   var newText = text.replace(textToHighlight, highlightedText);

   element.html(newText);
}

$("#search").keyup(function() {
   var value = this.value.toLowerCase().trim();

   removeHighlighting($("table tr em"));

   $("table tr").each(function(index) {
      if (!index) return;
      $(this).find("td").each(function() {
         var id = $(this).text().toLowerCase().trim();
         var matchedIndex = id.indexOf(value);
         if (matchedIndex === 0) {
            addHighlighting($(this), value);
         }
         var not_found = (matchedIndex == -1);
         $(this).closest('tr').toggle(!not_found);
         return not_found;
      });
   });
});
