jQuery DataTable PDF 导出表格单元格没有边框

Question

我正在使用 jQuery DataTable 来显示一个表格。此表包括一个“PDF 导出”按钮。导出显示 PDF 表单，但此表单在单元格周围没有边框。它只是一个文本表单（相对于 Excel 之类的表格）。 我想要类似的东西：对于每个单元格，但我似乎无法找到一种方法来做到这一点。任何人都可以帮忙吗？ 我设置此 DataTable 的 javascript 代码如下所示：

$("table[id$='jQueryDataTable']").dataTable(
            {
                aLengthMenu: [
                    [10, 25, 50, 100, 200, -1],
                    [10, 25, 50, 100, 200, "All"]
                ],
                iDisplayLength: -1,
                dom: 'Blrftip',
                buttons: [
                    {
                        extend: 'pdf',
                        title: 'Non Desctructive Inspection ' +
                            '   DATE: ' + d,
                        pageSize: 'A2',
                        orentation: 'landscape',
                        exportOptions: {  // This is IMPORTANT --- Monty
                            orthogonal: 'sort'
                        }//,
                        //function(){}
                    }
                ],
                aoColumnDefs: [{
                    "aTargets": [0, 1, 2, 3, 4, 5, 6],
                    "defaultContent": "",
                    "ordering": true
                }

});

添加此自定义功能：

var objLayout = {};
objLayout['hLineWidth'] = function(i) { return .8; };
objLayout['vLineWidth'] = function(i) { return .5; };
objLayout['hLineColor'] = function(i) { return '#aaa'; };
objLayout['vLineColor'] = function(i) { return '#aaa'; };
objLayout['paddingLeft'] = function(i) { return 8; };
objLayout['paddingRight'] = function(i) { return 8; };
doc.content[0].layout = objLayout;

完整的数据表实现是：

$('#datatable').DataTable({
        lengthMenu: [
            [4, 7, 10, 15, 20, -1],
            [4, 7, 10, 15, 20, "Todo"]
        ],
        responsive: true,
        paging: true,
        pagingType: "full_numbers",
        stateSave: true,
        processing: true,
        dom: 'Blftirp',
        buttons: [
            {
                extend: 'copyHtml5',
                text: '<i class="fa fa-files-o"></i>',
                titleAttr: 'Copy',
                exportOptions: {
                    columns: ':visible'
                }
            },
            {
                extend: 'pdfHtml5',
                text: '<i class="fa fa-file-pdf-o"></i>',
                titleAttr: 'PDF',
                extension: ".pdf",
                filename: "name",
                title: "",
                orientation: 'landscape',
                customize: function (doc) {

                    doc.styles.tableHeader = {
                        color: 'black',
                        background: 'grey',
                        alignment: 'center'
                    }

                    doc.styles = {
                        subheader: {

                            color: 'black'
                        },
                        tableHeader: {
                            bold: true,
                            fontSize: 10.5,

                        }
                    }

                    var objLayout = {};
                    objLayout['hLineWidth'] = function(i) { return .8; };

                    objLayout['hLineColor'] = function(i) { return '#aaa'; };
