Java_JXL 实现导出excel

导出模板样的excel 添加样式
按需求,某些数据为空的隐藏不导入

// 导出excel

handle_export() {

getInformExcel({pro: {}}).then(response => {

this.$message({ message: response.message, type: "success" });

var a = document.createElement("a");

a.setAttribute('download', "收费通知.xls");

a.setAttribute('href', '/unqualified/收费通知.xls');

a.click();

}, error => {

this.$message({ message: error.message, type: "success" });

var a = document.createElement("a");

a.setAttribute('download', "收费通知.xls");

a.setAttribute('href', '/unqualified/收费通知.xls');

a.click();

});

}
