This behaviour can be disabled completely using the <code>increment</code> column option, but it can also be modified to suit your requirements through use of the <code>step</code> column callback function.</p> <p>The <code>step</code> callback is executed for each cell in the auto-fill set and gives complete control over how data is incremented. The example below shows the step function being used on the <em>Salary</em> column to increment by 100, rather than 1 for each cell.</p> <p>For a complete description of the <code>step</code> callback, please refer to the <a href= "//datatables.net/extras/autofill/options">AutoFill documentation</a>.</p> </div> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr>
