If you need to insert an HTML element like one <div> or any other element before an existing element in the HTML Document you have to :

1. Get the element by ID :

var table = document.getElementById("clientsTable");

2. Create the HTML element

var div = document.createElement('DIV');
div.innerHTML = '<div> <h1> title </h1> </div>'

3. Insert the element

Here we will use insertBefore function to insert the created Div before the
recovered Table.

table.insertBefore(div,table.childNodes[0]);
