Datatable tabletool pdf导出宽度问题

Question

您好我在一个数据表中有35列。我正在使用表格工具将其导出为PDF。但是all the columns are rendered in one sheet as in without any X-scroll and the columns are crumpled together. 我使用以下代码。我希望你能解决我的问题。

              {
                    "sExtends": "pdf",
                    "sToolTip": "Download to pdf",
                    "sButtonClass": "fa fa-download ",
                    "sButtonText": "",
                    "mColumns": "all",
                    "sPdfSize": "tabloid",
                    "sTitle": gridConfig.pdfExportTitle,
                    "sMessage": gridConfig.pdfExportMsg
                }

谢谢
