If object is used, it allows configuration of resizable.columns and resizable.rows. If set to true, only column resizing will be enabled.

By default, column and row resizing is disabled.

Example - enable column resizing

<div id="grid"></div>
<script>
$("#grid").kendoGrid({
  columns: [
    { field: "name" },
    { field: "age" }
  ],
  dataSource: [
    { name: "Jane Doe", age: 30 },
    { name: "John Doe", age: 33 }
  ],
  resizable: true
});
</script>
