With this post, we will teach you how to rotate Grid column headers. 1. Add a new DIV tag to the HTML page and set its “id” to “jqxgrid”. 2. Create a new jqxGrid instance. Each column in the Grid has a ‘classname’ property which we set to a custom class called ‘rotate’.

  var data = new Array();
  var firstNames = [
      "Andrew", "Nancy", "Shelley", "Regina", "Yoshi", "Antoni", "Mayumi", "Ian", "Peter", "Lars", "Petra", "Martin", "Sven", "Elio", "Beate", "Cheryl", "Michael", "Guylene"];
  var lastNames = [
      "Fuller", "Davolio", "Burke", "Murphy", "Nagase", "Saavedra", "Ohno", "Devling", "Wilson", "Peterson", "Winkler", "Bein", "Petersen", "Rossi", "Vileid", "Saylor", "Bjorn", "Nodier"];
  var productNames = [
      "Black Tea", "Green Tea", "Caffe Espresso", "Doubleshot Espresso", "Caffe Latte", "White Chocolate Mocha", "Cramel Latte", "Caffe Americano", "Cappuccino", "Espresso Truffle", "Espresso con Panna", "Peppermint Mocha Twist"];
  var priceValues = [
      "2.25", "1.5", "3.0", "3.3", "4.5", "3.6", "3.8", "2.5", "5.0", "1.75", "3.25", "4.0"];
  for (var i = 0; i < 100; i++) {
      var row = {};
      var productindex = Math.floor(Math.random() * productNames.length);
      var price = parseFloat(priceValues[productindex]);
      var quantity = 1 + Math.round(Math.random() * 10);
      row["firstname"] = firstNames[Math.floor(Math.random() * firstNames.length)];
      row["lastname"] = lastNames[Math.floor(Math.random() * lastNames.length)];
      row["productname"] = productNames[productindex];
      row["price"] = price;
      row["quantity"] = quantity;
      row["total"] = price * quantity;
      data[i] = row;
  }
  var source = {
      localdata: data,
      datatype: "array"
  };
  var dataAdapter = new jqx.dataAdapter(source, {
      loadComplete: function (data) {},
      loadError: function (xhr, status, error) {}
  });

  const grid = new jqxGrid('#jqxgrid', {
      theme: 'energyblue',
      altrows: true,
      width: 500,
      columnsheight: 100,
      source: dataAdapter,
      columns: [{
          text: 'First Name',
          datafield: 'firstname',
          width: 100,
          classname: 'rotate'
      }, {
          text: 'Last Name',
          classname: 'rotate', 
          datafield: 'lastname',
          width: 100
      }, {
          classname: 'rotate', 
          text: 'Product',
          datafield: 'productname',
          width: 180
      }, {
          classname: 'rotate', 
          text: 'Quantity',
          datafield: 'quantity',
          width: 80,
          cellsalign: 'right'
      }, {
          classname: 'rotate', 
          text: 'Unit Price',
          datafield: 'price',
          width: 90,
          cellsalign: 'right',
          cellsformat: 'c2'
      }, {
          classname: 'rotate', 
          text: 'Total',
          datafield: 'total',
          width: 100,
          cellsalign: 'right',
          cellsformat: 'c2'
      }]
  });

3. The third and final step is to add our .rotate class to the Style section.

.rotate > div > div {
  display: flex;
  justify-content: center;
  transform: rotate(45deg);
  transform-origin: center center;
}
