如何添加类到jquery.datatables列？

问题描述

我为jquery.datatables制作了一张大桌子，这对我来说非常有用。

，但是我需要一个相对于其列的每个td元素设置的类名。

fo例如，我想要一列（包括th和所有td）有一个 class =volume。

有这个问题：

i使用此代码初始化该类，但它不工作。

I made a large table for jquery.datatables which is works great for me.
but i need a class name set to each td element relative to its column.
fo example i want a column (including th and all td's) have a class="volume".
there is this issues:
i use this code to initialize the class but it is not working.

"aoColumnsDefs": [
    { "sClass": "volume", "aTargets": [2] }
]

编辑：
我的表是动态创建和重新混合。它由一个js数组组成，我不喜欢触摸它。只需添加类名称

编辑：

我使用这个代码来表示我的表：

my table is created and refeshes dynamically. and it is made of a js-array which i prefer not to touch it ie. just to add class names

iuse this code to itialize my table:

$('#dataTable').dataTable({
    "aaData": dataCnt,
    "aoColumnsDefs": [
        { "sClass": "volume", "aTargets": [2] }
    ],
    "aoColumns": columnsHd,
    "bStateSave": true,//saving status in coockie
    "iCookieDuration": 10,//coockie life duration in seconds
    "sScrollX": "100%",
    "sScrollY": (winHei-200),
    "sDom": '<"H"RCfrl>t<p"F"i>',
    "oColVis": {
        "buttonText": "&nbsp;",
        "bRestore": true,
        "sAlign": "left"
    },
    "aLengthMenu": [[10, 25, 50, -1], [10, 25, 50, "All"]]
});

我希望它有助于
* EIDT：* >
columnsHd 是一个从我的json头创建动态的数组，现在是：

i hope it helps *EIDT: *
columnsHd is an array which is created dynamicaly from my json headers and now is exactly:

[
{ "sTitle": "macaddr" },
{ "sTitle": "lat" },
{ "sTitle": "ip" },
{ "sTitle": "clientname" },
{ "sTitle": "relay0mask" },
{ "sTitle": "relay0stat" },
{ "sTitle": "relay1stat" },
{ "sTitle": "clientid" },
{ "sTitle": "bldname" },
{ "sTitle": "uptime" },
{ "sTitle": "current" },
{ "sTitle": "temperature" },
{ "sTitle": "softver" },
{ "sTitle": "volume" },
{ "sTitle": "hardver" },
{ "sTitle": "relay1mask" },
{ "sTitle": "pic" },
{ "sTitle": "comment" },
{ "sTitle": "lon" },
{ "sTitle": "rtt" },
{ "sTitle": "bldaddr" },
 ]

推荐答案

我的猜测是aoColumns：columnsHd，覆盖aoColumnsDefs：[ {sClass：volume，aTargets：[2]}，]，

尝试在代码

或者直接在aoColumns中添加类：columnsHd，
喜欢这个sClass：volume

完成代码：

将 {sTitle：ip}，转换为 {sTitle：ip，sClass：volume}， / code>

try changing { "sTitle": "ip" }, into { "sTitle": "ip", "sClass": "volume" },

并删除

"aoColumnsDefs": [
    { "sClass": "volume", "aTargets": [2] }
],
