function SetupColumnSearch(table, columnTitles) {
    /* Setup column-level search input fields. */
    $(table.table().header()).find('th').each( function () {
        var title = $(this).text();
        if (columnTitles.indexOf(title) > -1)
            $(this).html( '<input type="text" placeholder="'+title+'" class="column_search" oninput="stopPropagation(event)" onclick="stopPropagation(event);"/>' );
    } );

    /* Setup column-level searches on enter key only. */
    table.columns().every( function () {
        var column = this;
        $( 'input.column_search', this.header() ).on( 'keydown', function (e) {
            /* Ignore all keyup events except for return keys */
            if(e.type === 'keydown' && e.keyCode === 13){
              e.preventDefault();
              
              
            /* Avoid a DataTables bug where invisible columns show up */
            if (column.visible()) {
                table.column( column.index() ).search( this.value ).draw();
            }
            } 
        } );
    } );
}

function stopPropagation(evt) {
    if (evt.stopPropagation !== undefined) {
        evt.preventDefault();
        evt.stopPropagation();
    } else {
        evt.cancelBubble = true;

$(document).ready(function() {

  SetupColumnSearch(oTable, ["First", "Last"])
