Java Class Library Excel Templaater Framework Introduction Guide

Java Class Library Excel Templaater Framework Introduction Guide Overview: Java Library Excel Templator is a powerful and easy -to -use framework that is used to generate and operate Excel documents using Java code.Whether it is a simple report or a complex Excel template, Excel Templateer can provide convenient and efficient solutions.This guide will introduce the basic use of Excel Templateer and provide some Java code examples. 1. Installation and configuration Excel Templater: First, you need to download the jar file of Excel Template and include it in your Java project.Create an Excel Templateer instance in your project.You can use the following code to create an Excel Templateer instance: ExcelReport report = new ExcelReport(); 2. Create Excel template: Excel Templateer can generate corresponding reports according to the Excel template.You can use Microsoft Excel or other electronic table software to create a template file and define the layout and format of the report in the template file.Make sure that the data position to be filled with a specific tag in the template.For example, you can use "<< >>" in the cell to indicate the data that needs to be filled. 3. Fill in data: Excel Templater allows you to dynamically fill the data in the Excel report using Java code.First of all, you need to load the template to the Excel Templator instance, and then fill the data with a specific method.The following is a sample code that fills the data to the EXCEL report: // Load the template report.loadTemplate("template.xls"); // Create a data source List<Employee> employees = new ArrayList<Employee>(); employees.add(new Employee("John Doe", 30, "Engineer")); employees.add(new Employee("Jane Smith", 28, "Manager")); // Data input report.addData("employees", employees); // Save the report report.generateReport("report.xls"); In the above example code, we first loaded a template file named "Template.xls".Then, we created a data source containing employee information and named it "Employees".Finally, we use the "addata ()" method to fill the corresponding position in the template.By calling the "GeneralReport ()" method, we can save the report that fills the data in a file called "Report.xls". 4. Custom report: Excel Template also allows you to customize the layout and format of the report as needed.You can use the Java code to control the style of the report, such as fonts, colors and borders.The following is an example code of a custom report style: Style style = new Style(); style.setFont(new Font("Arial", 12, Color.RED)); style.setBorder(new Border(Color.BLACK, 1)); report.setStyle("employees", "name", style); In the above sample code, we first created a custom style object and set the font, size, and color.Then, we use the "SetStyle ()" method to apply the style to a specific location in the template (the "name" column in the data source "Employees"). in conclusion: Through the Excel Templateer framework, you can easily use the Java code to generate and operate the Excel document.You can create and customize Excel templates, fill the data with Java code, and control the layout and style of the report.I hope this entry guide will help you start using the Excel Templateer framework. Note: The above example code is simplified, and you may need to be adjusted and modified according to your specific needs.
