  1、插入一行

•  将数据插入到第一行

$("#alarm").prepend("<tr><td></td></tr>");

$("#alarm").append("<tr><td></td></tr>");

$("<tr><td></td></tr>").insertAfter($("#alarm tr:eq(1)"));

2、删除一行 

•   删除第一行 

$("#alarm tr:first").remove();

•  删除最后一行 

$("#alarm tr:last").remove();

•  删除指定行 

$("#alarm tr:eq(3)").remove();

3、改变行的颜色

$("#alarm tr:even").css("color", "#0000FF");
$("#alarm tr:odd").css("color", "#000000");

$("#bottom_right_h").attr("src", "../Images/Icon/face.gif");
   var alarmListInfo = eval('(' + info + ')');
    var count = $('#alarm').find("tr").length - 1;
    tr_id = $("#alarm>tbody>tr:first").attr("id");
    tr_id++;
    str = "<tr id = '" + tr_id + "'><td width='20%' id='" + alarmListInfo.TerminalID + "'>"
            + "TerminalID:<a href='#' onclick='javascript:MarkerVehicleByTerminalID(" + alarmListInfo.TerminalID + ")'>" + alarmListInfo.TerminalID+"</a><br/>"
            + "AlarmName:<font color='red'>" + alarmListInfo.AlarmName + "</font><br/>"
            + "AlarmInfo:" + alarmListInfo.AlarmInfo + "</td>"  
            + "</tr>";
    $('#alarm').append(str);
    $("tr:even").css("background", "#EAF2D3");  
    $("tr:odd").css("background", "#ffffff");        
    if (count > 2) {
        delAlarmListTR();
    }

//删除一行 $("#alarm td").each(function () {
        if ($(this).attr('id')) {
            ids.push($(this).attr('id'));
            $(this).parents('tr').remove();
        }
    });
