对表进行排序，但不要移动一列

Question

我想对下表进行排序，但同时我不希望编号列移动，而是在其他列移动时应保持固定。关于我应该怎么做的任何想法

＆＃13;

＆＃13;

$(document).ready(function() { 
    $("#myTable").tablesorter({ 
        // pass the headers argument and assing a object 
        headers: { 
            // assign the first column not to sort
          
           0: { 
                // disable it by setting the property sorter to false 
                sorter: false 
            }, 
        } 
    }); 
});

Answer 1

您可以绑定到sortEnd事件，只需将新文本写入第一列。

以下代码利用了

的事实

• jQuery＆＃39; s .text()接受回调函数来计算并返回每个匹配元素的新文本​​（http://api.jquery.com/text/）
• 此回调函数接收（从零开始）元素索引作为第一个参数，因此您不需要保留单独的计数器变量

＆＃13;

$(function() { 
    $("#myTable").tablesorter({ 
        headers: { 
            0: { 
                sorter: false 
            }, 
        } 
    }).on("sortEnd", function () {
        $(this).find('tbody td:first-child').text(function (i) {
            return i + 1;
        });
    });
});
