  $(".cat").dblclick(function() {
    var OriginalContent = $(this).text();
    $(this).addClass("cellEditing1")
    $(this).html("<input id='value' type='text' value='" + OriginalContent + "' />");
  })


  $('tr').click(function() {
    $('tr').removeClass('selected1');
    $(this).addClass('selected1');

  });

  $(".cat").on("click", function() {
    $(this).removeClass('selected')
    $(this).addClass('selected');
  });
  $(".cat1").on("click", function() {
    $(this).removeClass('selected2')
    $(this).addClass('selected2');
  });

  $("#key").click(function() {

    var sl = parseInt($(".selected").css("padding-left"));
    sl = sl >= 20 ? "20" : "+=20";

    $(".selected").css({
      "padding-left": sl

    });
    var sq = parseInt($(".selected2").css("padding-left"));
    sq = sq >= 40 ? "40" : "+=20";

    $(".selected2").css({
      "padding-left": sq

    });
    $(".cat.selected").each(function() {
      var prevTd = $(this).closest('tr').prev('tr').find('td:eq(' + $(this).index() + ')');
      console.log('Current td index: ' + $(this).index());
      console.log('Previous td content: ' + prevTd.text());

      prevTd.addClass("mainfunctionstyle");
      prevTd.find('input').addClass("mainfunctionstyle");



    });

    $(".cat1.selected2").each(function() {

      var paddingLeftpl = parseInt($(this).css("padding-left"));
      if (paddingLeftpl == 40) {
        $(".selected2").addClass("taskstyle");

Why do the `.cat` and `.cat1` click functions remove and add the same class to `$(this)`? — Barmar, Jul 09 '16 at 10:21
But it doesn't remove the TD selection, since both of them are just operating on `$(this)`. Did you mean to do `$('.cat').removeClass('selected')`? — Barmar, Jul 09 '16 at 10:25
yes ,you just see the out put now TR selection and non selection is ok but the TD selection remove is not working — aswathy, Jul 09 '16 at 10:27
The problem is that you're putting the classes on both the TR and the TD. When you click on a different row, you remove the class from the old TR, but you leave it on the old TD, so it's still blue. — Barmar, Jul 09 '16 at 10:30

I think your problem is having this in your code:

$(".cat").on("click", function() {
    $(this).removeClass('selected')
    $(this).addClass('selected');
  });
  $(".cat1").on("click", function() {
    $(this).removeClass('selected2')
    $(this).addClass('selected2');
  });

You don't need to have a listener on the td elements since you have one on the tr elements doing the job. There's something called event propagation that means by default if you click an element, the parent of the clicked element will have its click element triggered as well, therefore you don't need to handle td clicks if you're looking for manipulating a tr.

$(function() {
  $(".cat").dblclick(function() {
    var OriginalContent = $(this).text();
    $(this).addClass("cellEditing1")
    $(this).html("<input id='value' type='text' value='" + OriginalContent + "' />");
  })


  $('tr').click(function() {
    $('tr').removeClass('selected1');
    $(this).addClass('selected1');

  });
  $("#key").click(function() {

    var sl = parseInt($(".selected").css("padding-left"));
    sl = sl >= 20 ? "20" : "+=20";

    $(".selected").css({
      "padding-left": sl

    });
    var sq = parseInt($(".selected2").css("padding-left"));
    sq = sq >= 40 ? "40" : "+=20";

    $(".selected2").css({
      "padding-left": sq

    });
    $(".cat.selected").each(function() {
      var prevTd = $(this).closest('tr').prev('tr').find('td:eq(' + $(this).index() + ')');
      console.log('Current td index: ' + $(this).index());
      console.log('Previous td content: ' + prevTd.text());

      prevTd.addClass("mainfunctionstyle");
      prevTd.find('input').addClass("mainfunctionstyle");



    });

    $(".cat1.selected2").each(function() {

      var paddingLeftpl = parseInt($(this).css("padding-left"));
      if (paddingLeftpl == 40) {
        $(".selected2").addClass("taskstyle");
        $(".selected2").find('input').addClass("taskstyle");
      }

    });
  });

I just made some modification in you code. Since selected, selected1 and selected2 have same css properties. I used only selected class. And i made a modification in js like this :

$(".selected1").removeClass('selected1')
$(this).addClass('selected1');

$(function() {
  $(".cat").dblclick(function() {
    var OriginalContent = $(this).text();
    $(this).addClass("cellEditing1")
    $(this).html("<input id='value' type='text' value='" + OriginalContent + "' />");
  })


  $('tr').click(function() {
    $('.selected1').removeClass('selected1');
    $(this).addClass('selected1');

  });

  $(".cat").on("click", function() {
    $(".selected1").removeClass('selected1')
    $(this).addClass('selected1');
  });
  $(".cat1").on("click", function() {
    $('.selected1').removeClass('selected1')
    $(this).addClass('selected1');
  });

  $("#key").click(function() {

    var sl = parseInt($(".selected").css("padding-left"));
    sl = sl >= 20 ? "20" : "+=20";

    $(".selected").css({
      "padding-left": sl

    });
    var sq = parseInt($(".selected2").css("padding-left"));
    sq = sq >= 40 ? "40" : "+=20";

    $(".selected2").css({
      "padding-left": sq

    });
    $(".cat.selected").each(function() {
      var prevTd = $(this).closest('tr').prev('tr').find('td:eq(' + $(this).index() + ')');
      console.log('Current td index: ' + $(this).index());
      console.log('Previous td content: ' + prevTd.text());

      prevTd.addClass("mainfunctionstyle");
      prevTd.find('input').addClass("mainfunctionstyle");



    });

    $(".cat1.selected2").each(function() {

      var paddingLeftpl = parseInt($(this).css("padding-left"));
      if (paddingLeftpl == 40) {
        $(".selected2").addClass("taskstyle");
        $(".selected2").find('input').addClass("taskstyle");
      }

    });
  });

Fiddle here.

Why use a fiddle instead of Stack Snippet? And you need to explain what you changed and why. No one is going to read through all the code trying to figure out what the differences are. — Barmar, Jul 09 '16 at 10:36

I hope it help you ! I used toggleclass of jquery : http://www.w3schools.com/jquery/html_toggleclass.as

The toggleClass() method toggles between adding and removing one or more class names from the selected elements.

This method checks each element for the specified class names. The class names are added if missing, and removed if already set - This creates a toggle effect.

However, by using the "switch" parameter, you can specify to only remove, or only add a class name.

$(document).ready(function() {
    $('#example tbody').on( 'click', 'tr', function () {
        $(this).toggleClass('highlighted');
    } );
} );

.highlighted {
    color: #261F1D;

You need to explain what you changed and why, not just post a bunch of code. — Barmar, Jul 09 '16 at 10:35
I used toggleclass of jquery. The toggleClass() method toggles between adding and removing one or more class names from the selected elements. This method checks each element for the specified class names. The class names are added if missing, and removed if already set - This creates a toggle effect. — Tính Ngô Quang, Jul 09 '16 at 10:40
