Hi,

You can write something like this in search function

document.getElementById('datatable-search-input').addEventListener('input', (e) => {
  instance.search(e.target.value);
  const td = document.querySelector('td')
  if (td.innerText === "No matching results found"){
    td.setAttribute('colspan', 3)
    td.style.textAlign = 'center'
  }
});

Here is the snippet https://mdbootstrap.com/snippets/standard/d-wajszczuk/3520038#js-tab-view.

Keep coding,
Dawid
