Table headers coming out as [object Object]

[RayburnTrading]

Hi,

const tableJson = { 
            "headers": [
              { "label":"Name", "property":"name", "width":100 },
              { "label":"Age", "property":"age", "width":100 },
              { "label":"Year", "property":"year", "width":100 }
            ],
            "datas": [
              { "name":"bold:Name 1", "age":"Age 1", "year":"Year 1" },
              { "name":"Name 2", "age":"Age 2", "year":"Year 2" },
              { "name":"Name 3", "age":"Age 3", "year":"Year 3",
                "renderer": "function(value, i, irow){ return value + `(${(1+irow)})`; }"
              }
            ],
            "rows": [
              [ "Name 4", "Age 4", "Year 4" ]
            ],
            "options": {
              "width": 300
            }
          };

doc.table(tableJson);

This code taken from the official example is giving me column headers of [object Object]?

PDFKit: 0.13.0 pdfkit-table: 0.1.99

Any advice?

Thanks.
