我有三个数组“listA、listB、listC”，我想从这些列表创建三个表。到目前为止，我只能创建一个表，而且我无法弄清楚如何使用文档来做我想做的事情。 fluentreports documentaiton
这是我到目前为止所拥有的，我正在查看 .addReport 并尝试使用它，但我收到错误“未处理的拒绝 TypeError:rpt.addReport 不是函数”。我可以获得一些显示多个表格的帮助吗？我的代码如下。
const express = require('express');
const db = require('../config/db');
const router = new express.Router();
const PDFDocument = require('pdfkit')
const Report = require('fluentreports').Report
var fs = require("fs")
router.get('/getpdf', (req, res) => {
res.type('application/pdf');
// Our Simple Data in Object format:
var results1;
db.sequelize.query("SELECT device.\"deviceID\", device.\"deviceType\", event.data, event.\"event_time_stamp\" FROM public.device, public.event WHERE event.\"device_deviceID\" = device.\"deviceID\"").spread((results, metadata) => {
//console.log(results)
var listA = [];
var listB = [];
var listC = [];
results.map(cv => {
switch (cv.deviceType) {
case 'type1':
listA.push(cv);
break;
case 'type2':
listB.push(cv);
break;
case 'type3':
listC.push(cv);
break;
}
});
listA.map(cv => {
[cv.quantity, cv.additional] = cv.data.split(',');
cv.deviceType = 'Poison Grizach';
cv.quantity = cv.quantity + '%'
delete cv.data;
});
listB.map(cv => {
[cv.mouse, cv.rat, cv.other, cv.additional] = cv.data.split(',');
cv.deviceType = 'Non-Poison Grizach';
delete cv.data;
});
listC.map(cv => {
[cv.flies, cv.quantity, cv.additional] = cv.data.split(',');
cv.deviceType = 'Insect Lamp';
cv.flies = cv.flies + '%'
delete cv.data;
});
var all = listA.concat(listB).concat(listC)
var headerFunction = function(Report) {
Report.print("Device Scans", {fontSize: 22, bold: true, underline:true, align: "center"});
Report.newLine(2);
Report.band([
{data: 'Device Type', width: 100},
{data: 'Quantity', width: 50},
{data: 'Mouse', width: 50},
{data: 'Rat', width: 50},
{data: 'Other', width: 50},
{data: 'Additional', width: 50},
{data: '% Myxi', width: 50},
]);
};
// Create a Report
var rpt = new Report(res,({fontSize: 10}))
.pageHeader( ["Device Scans"] ) // Add a simple (optional) page Header...
.margins(40)
.data( listA ) // Add some Data (This is required)
.pageHeader(headerFunction)
.detail( [ ['deviceType', 100], ['quantity', 50] , ['mouse', 50], ['rat', 50], ['other', 50], ['additional', 50] , ['flies', 50]]) // Layout the report in a Grid of 200px & 50px
.render()
var rpt2 = new Report(res,({fontSize: 10}))
.pageHeader( ["Device Scans"] ) // Add a simple (optional) page Header...
.margins(40)
.data( listB ) // Add some Data (This is required)
.pageHeader(headerFunction)
.detail( [ ['deviceType', 100] , ['mouse', 50], ['rat', 50], ['other', 50], ['additional', 50] ]) // Layout the report in a Grid of 200px & 50px
rpt.addReport(rpt2)
})
});
module.exports = router;最佳答案
解决方案如下。父报表 rpt 包含在“同级”报表的创建中。在此实现中，使用 isSibling: true 选项从最后一个同级调用 Render。头文件被定义为给出列名称

};
// Create a Report
var rpt = new Report(res,({fontSize: 10}))
.titleHeader("Device Scans")
.margins(40)
.data( {}) // Add some Data (This is required)
var rpt1 = new Report(rpt,({fontSize: 10}))
.margins(40)
.data( listA ) // Add some Data (This is required)
.pageHeader(headerFunction)
.detail( [ ['deviceType', 100], ['quantity', 50] , ['additional', 50]]) // Layout the report in a Grid of 200px & 50px
