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.
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)
