我不得不使用一些jquery转换到第一行到thead工作.

示例如下：

$(document).ready(function () {
    var $theadCols = $("#ContentPlaceHolder1_grdCashflow  tr:first-child"),$table = $("#ContentPlaceHolder1_grdCashflow");

    // create thead and append <th> columns
    $table.prepend("<thead/>");
    $table.find("thead").append($theadCols);

    // init stickyHeader
    $table.floatThead();

    //$table = $("#ContentPlaceHolder1_grdCashflow");
    $table.dataTable(
    {
        "paging": false,"ordering": false,"dom":'<"top"fi>rt<"bottom"><"clear">'
    }
    );
});
