jqGrid：如何在启用表单编辑的情况下在每行中添加编辑和删除按钮？

我有一个如下图所示的网格：

目前，我在页脚中有添加，编辑，删除按钮。我需要在每行中都有“编辑”和“删除”按钮。当我单击每一行中的“编辑”按钮时，它将显示编辑表单，而当单击“提交”时，它将数据保存到数据库中。

我的代码如下所示：

    $(document).ready(function () {
        //jQuery.extend(jQuery.jgrid.defaults, { altRows:true });
        $("#list_records").jqGrid({
            url: 'ajaxELearningFetchTableData.php?table=GET_TRAINING_TYPE',
            //url: 'server.php',
            editurl: 'ajaxELearningSaveTrainingType.php',
            datatype: "json",
            colNames: ["TRAINING TYPE ID", "TRAINING TYPE NAME", "REMARKS"],
            colModel: [
                {
                    label: 'TRAINING TYPE ID',
                    name: 'TRAINING_TYPE_ID',
                    index: 'TRAINING_TYPE_ID',
                    editable: true,
                    sortable: true,
                    sorttype: "text",
                    editoptions: {readonly: "readonly"},
                    width: 40
                },
                {
                    label: 'TRAINING TYPE NAME',
                    name: 'TRAINING_TYPE_NAME',
                    index: 'TRAINING_TYPE_NAME',
                    width: 120,
                    editable: true, // must set editable to true if you want to make the field editable
                    editoptions: {size: 50, maxlength: 80},
                    editrules: {required: true, maxlength: 80},
                    sortable: true,
                    sorttype: "text",
                    // set options related to the layout of the Edit and Add Forms
                    formoptions: {
                        colpos: 1, // the position of the column
                        rowpos: 2, // the position of the row
                        label: "Training Type Name:", // the label to show for each input control  
                        elmsuffix: "(*)"

                    }
                },
                {
                    label: 'REMARKS',

                    }
