回答:

public void AddSignature() {

Workbook wb = new Workbook();

ISignature signature = wb.getSignatures().addSignatureLine(wb.getActiveSheet(), 100, 50);

ISignatureSetup setup = signature.getSetup();

setup.setShowSignDate(false);

setup.setAllowComments(false);

setup.setSigningInstructions("Please check the content before signing");

setup.setSuggestedSignerEmail("example@example.com");

setup.setSuggestedSignerLine2("Commander (Balanced)");

wb.save("output/SignatureLines.xlsx");

}
