In the table, the first column indicates the position ‘sticky’, which opens a drop-down menu position: absolute. But the subsequent column overlaps the menu that opens.

Example: https://codepen.io/rowlin9/pen/qBGmEKb

.dropbtn {
  background-color: #04aa6d;
  color: white;
  padding: 16px;
  font-size: 16px;
  border: none;
  z-index: 99999;
}

/* The container <div> - needed to position the dropdown content */
.dropdown {
  position: relative;
  display: inline-block;
}

/* Dropdown Content (Hidden by Default) */
.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f1f1f1;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 99999;
}

/* Links inside the dropdown */
.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

/* Change color of dropdown links on hover */
.dropdown-content a:hover {
  background-color: #ddd;
}

/* Show the dropdown menu on hover */
.dropdown:hover .dropdown-content {
  display: block;
}

/* Change the background color of the dropdown button when the dropdown content is shown */
.dropdown:hover .dropbtn {
  background-color: #3e8e41;
  z-index: 99999;
}

I tried to set z-index – it didn’t help.

Maybe someone has come across something like this. Thank you in advance.
