How to Create HTML table with fixed header but dynamic column

Question

I have two HTML buttons, one named 3days and other named week. Based on the click of any of these buttons I need to create a dynamic table with Fixed Headers but dynamic column.

Answer 1

Updated Code:

   $("table").hide();
$("#3").click(function(){
    $("table").show();
    $("th:gt(2)").hide();  
    $("td:gt(2)").hide();  
});

$("#7").click(function(){
     $("table").show();
    $("th:lt(7)").show();  
    $("td:lt(7)").show();  
});
