我从先前答案的

I modified the demo from the previous answer to the following which display now

我在演示CSS类时使用了该类，除了下划线以外，我还更改了文本的颜色

I used for the demo the CSS class where I additionally to underlining changed the color of the text

.sortedColumnHeader > div { text-decoration: underline; color: blue; }

如果我们向前播放，则可以仅使用"ui-state-highlight"进行突出显示(请参见另一个演示).列标题与标准列的区别可能更大:

If we play forward we can use just the 'ui-state-highlight' for the highlighting (see another demo). The column header will be probably even too much distinguish from the standard column:

对应的代码是

var $grid = $("#list"), colModel, sortName;

// create the grid
$grid.jqGrid({
    // all typical jqGrid parameters
    onSortCol: function (index, idxcol, sortorder) {
        if (this.p.lastsort >= 0 && this.p.lastsort !== idxcol
                && this.p.colModel[this.p.lastsort].sortable !== false) {
            // show the icons of last sorted column
            $(this.grid.headers[this.p.lastsort].el)
                .find(">div.ui-jqgrid-sortable>span.s-ico").show();
            $(this.grid.headers[this.p.lastsort].el).removeClass('sortedColumnHeader');
        }
        $(this.grid.headers[idxcol].el).addClass('sortedColumnHeader');
    }
});

// show sort icons of all sortable columns
colModel = $grid.jqGrid('getGridParam', 'colModel');
sortName = $grid.jqGrid('getGridParam', 'sortname');
$('#gbox_' + $.jgrid.jqID($grid[0].id) +
    ' tr.ui-jqgrid-labels th.ui-th-column').each(function (i) {
    var cmi = colModel[i], colName = cmi.name;

    if (cmi.sortable !== false) {
        // show the sorting icons
        $(this).find('>div.ui-jqgrid-sortable>span.s-ico').show();
    } else if (!cmi.sortable && colName !== 'rn' && colName !== 'cb' && colName !== 'subgrid') {
        // change the mouse cursor on the columns which are non-sortable
        $(this).find('>div.ui-jqgrid-sortable').css({cursor: 'default'});
    }
    if (cmi.name === sortName) {
        $(this).addClass('sortedColumnHeader');
    }
});

最后，我想再参考一个旧答案，其中显示了另一种复杂的方法来突出显示已排序的列.

At the end I want to reference one more old answer where it's shown another sophisticated method to highlight the sorted column.
