ColSpan is buggy

[sdancer75]

I anticipated that the last row of the table would be merged using colSpan, but it doesn't seem to work.

Example of the code

   const handleViewPDF = () => {
      const raw = [
         { name: 'Torrey Becker', email: '[email protected]', city: 'Cremin bury' },
         { name: 'Jared Corwin', email: '[email protected]', city: 'Bergstrom land' },
         { name: 'Jocelyn Zboncak', email: '[email protected]', city: 'Fritsch town' },
         { name: 'Emilio Wyman', email: '[email protected]', city: 'North Noah mouth' },
         { name: '_Torrey Becker', email: '[email protected]', city: 'Cremin bury' },
         { name: '_Jared Corwin', email: '[email protected]', city: 'Bergstrom land' },
         { name: '_Jocelyn Zboncak', email: '[email protected]', city: 'Fritsch town' },
         { name: '_Emilio Wyman', email: '[email protected]', city: 'North Noah mouth' },
      ];
      // eslint-disable-next-line
      const doc = new jsPDF('p', 'pt');

      const body = [];

      // eslint-disable-next-line
      for (let i = 0; i < raw.length; i += 1) {
         const row = [];
         // eslint-disable-next-line
         for (let key in raw[i]) {
            row.push(raw[i][key]);
         }

         body.push(row);
      }

      body.push({
         colSpan: 3,
         content: 'Merged (colSpan=3)',
         styles: { valign: 'middle', halign: 'center' },
      });

      doc.autoTable({
         startY: 60,
         body,
         theme: 'grid',
      });
      doc.save(`report.pdf`);
   };
