Re-arrange the DataTable Columns


Re-arrange the DataTable Columns. DataTable has wide range of supports and customization, you can do a lot with your HTML tables. Let’s try re arranging the columns in DataTable. For the demo purpose, i am going to make an html table and a pre data with help of that we will make the demo working one,

<table id="example" class="display" cellspacing="0" width="100%">
</table>
<button id="reorder1">Reorder to Position, Salary etc.</button>
<button id="reorder2">Reorder to Office, Start date etc.</button>

The above one is HTML with help of following JS, we will work through it.

];

var table = $('#example').DataTable( {
    data: dataSet,
    columns: [
        { title: "Name" },
        { title: "Position" },
        { title: "Office" },
        { title: "Extn." },
        { title: "Start date" },
        { title: "Salary" }
    ],
    colReorder: true
});

var originalOrder = [
    "Name", "Position", "Office", "Extn.", "Start date", "Salary"
];

// Returns an array of original column indexes from an array of column names
var getNewOrder = function(columns){
	var indexes = [];
    
    // Search for the index of the named column
    for (var i = 0; i < columns.length; i++){
    	indexes.push(originalOrder.indexOf(columns[i]));
    }
    
    // Add the rest of indexes in their original order
    for (var i = 0; i < originalOrder.length; i++){
    	if (indexes.indexOf(i) < 0){
        	indexes.push(i);    
        }
    }
    
    return indexes;
};

$('#reorder1').click(function(e){
    // Pass it true so colReorder knows these are original indexes
    table.colReorder.order(getNewOrder(["Position","Salary"]), true);
});

$('#reorder2').click(function(e){
    // Pass it true so colReorder knows these are original indexes
    table.colReorder.order(getNewOrder(["Office","Start date"]), true);
});

Here these two are re arranging the columns.

$('#reorder1').click(function(e){
    // Pass it true so colReorder knows these are original indexes
    table.colReorder.order(getNewOrder(["Position","Salary"]), true);
});

$('#reorder2').click(function(e){
    // Pass it true so colReorder knows these are original indexes
    table.colReorder.order(getNewOrder(["Office","Start date"]), true);
});

I hope, you can get it working.
