React Convert Div and Table Component Into PDF With Multiple Pages and CSS

As the title says I need to be able to convert the table into a pdf with a header across multiple pages (just like I have it doing in print).

I've found several sources on how to convert react components to a pdf file. But none cover the combination of requiring a component/table spread across multiple pages and importing the CSS you have too. I have it working for print using the react-to-print Library, but I can't seem to find anything for a pdf. The react-pdf library forms stays you cannot use html elements with it.

full code - https://codesandbox.io/s/react-table-to-pdf-m15em?file=/src/App.js

The pdf function...

  exportPdf = () => {
    const state = this.props.listOfStates.find(state => state.id === this.state.selectedStateId);
    const school = this.props.listOfSchools.find(school => school.id === this.state.selectedSchoolId);
    Promise.resolve(this.setState({ ...this.state, selectedStateNamePdf: state.stateName, selectedSchoolNamePdf: school.schoolName }))
    .then(() => {
      const input = document.getElementById('pdf-element');
      html2canvas(input)
        .then((canvas) => {
          const imgData = canvas.toDataURL('image/png');
          const pdf = new jsPDF();
          pdf.addImage(imgData, 'JPEG', 0, 0);
          pdf.addPage();
          pdf.addImage(imgData, 'JPEG', 0, 0);
          pdf.save("download.pdf");
        })
      ;
    })
  }

The pdf component...

class PdfReportContent extends Component {
  render(){
    const { selectedReportDetails, stateName, schoolName, startDate, endDate } = this.props;
    return (
      <div id="pdf-element" style={{maxWidth: "210mm", width: "100%", height: "100%", position: "relative", margin: "0"}}>
        <div style={{display: "block"}}>
          <div style={{width: "100%", display: "flex", justifyContent: "space-between", padding: "1vh 2.5vh 0"}}>
            <div>
              <h2 className="header-title-one">SCHOOL</h2>
              <h2 className="header-title-two">REPORT</h2>
            </div>
            <div style={{display: "flex"}}>
              <div style={{display: "inline-block", textAlign: "right"}}>
                <h5>{stateName}</h5>
                <h5>{schoolName}</h5>
                <p>{startDate} - {endDate}</p>
              </div>
            </div>
          </div>
          <hr />
          <h3 style={{margin: "10px 0 0 2.5vh"}}>REPORT RESULTS</h3>
        </div>
        <div id="print-list-body">
          {selectedReportDetails.map((classDetails, indexOne) => 
            <div key={indexOne} style={{maxWidth: "200mm", width: "100%", margin: "40px auto 0 auto", boxSizing: "border-box"}}>
              <h2 style={{marginBottom: "10px", color: "#01A3E0"}}>{classDetails.className}</h2>
              {classDetails.classes.map((dateTable, indexTwo, classes) =>
                <table key={indexTwo} className="tbl-reports-list">
                  <tbody>
                    <tr>
                      <th>{dateTable.date}</th>
                      <th>Students</th>
                      <th>Grades</th>
                      <th>Assignment</th>
                      <th>Attendance</th>
                    </tr>
                    {dateTable.instructors.map((instructor, indexThree, instructorRows) =>
                      instructor.students.map((row, indexFour, studentRows) =>
                        indexTwo === classes.length-1 ? 
                        <tr key={indexFour} style={indexFour === studentRows.length-1 ? { borderBottom: "2px solid #01A3E0"} : {}}>
                          {indexFour === 0 ?
                          <td>
                              <h5>{instructor.instructorName}</h5>
                          </td> : <td />
                          }
                          <td style={{backgroundColor: "#ffffff"}}>{row.name}</td>
                          <td style={row.isHonorStudent ? {backgroundColor: "#ffffff"} : {backgroundColor: "#ffedbc"}}>{row.grade}</td>
                          <td style={{backgroundColor: "#ffffff"}}>{row.assignment}</td>
                          <td style={{backgroundColor: "#ffffff"}}>{row.attendance}</td>
                        </tr> : 
                        <tr key={indexFour} style={indexFour === studentRows.length-1 && indexThree !== instructorRows.length-1 ? { borderBottom: "2px solid #01A3E0"} : {}}>
                          {indexFour === 0 ?
                          <td>
                              <h5>{instructor.instructorName}</h5>
                          </td> : <td />
                          }
                          <td style={{backgroundColor: "#ffffff"}}>{row.name}</td>
                          <td style={row.isHonorStudent ? {backgroundColor: "#ffffff"} : {backgroundColor: "#ffedbc"}}>{row.grade}</td>
                          <td style={{backgroundColor: "#ffffff"}}>{row.assignment}</td>
                          <td style={{backgroundColor: "#ffffff"}}>{row.attendance}</td>
                        </tr>
                      )
                    )}
                  </tbody>
                </table>
              )}
            </div>
          )}
        </div>
      </div>
    );
  }
}

Steps to reproduce issue:

If anyone can fork the project in the codesandbox link and show me what I'm missing it would be much appreciated.

You can use this code:

...
const input = document.getElementById("pdf-element");
const pdf = new jsPDF('p', 'pt', 'a4');
    pdf.html(input).then(() => {
      pdf.save('test.pdf');
    });
...

jsPdf has a method to render html, you can use it instead of creating the document manually with images, this is the required change to your code:

   ...
   const input = document.getElementById("pdf-element");
   const pdf = new jsPDF({ unit: "px", format: "letter", userUnit: "px" });
   pdf.html(input, { html2canvas: { scale: 0.57 } }).then(() => {
     pdf.save("test.pdf");
   });
   ...

Noticed that I tweak some configs in jsPdf object creation and when calling .hmtl(), for some reason the pdf gets zoomed in, that's why I addded the scale option for html2canvas (this might as well be platform/browser dependant)
