除了能够添加以外,还要能删除,具体要怎么实现呢?
语言是java
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");
}
