Use Light Excel Reader framework to operate the style and format in Excel file

Use Light Excel Reader framework to operate the style and format in Excel file Light Excel Reader is a lightweight Java framework for handling Excel files.It provides rich functions and can easily operate the styles and formats in the Excel file.This article will introduce how to use the Light Excel Reader framework to implement the operation of style and format.If necessary, the Java code example will be provided. First, we need to add Light Excel Reader to the project.You can add it to the construction file of the project through Maven or Gradle.The following is an example of adding Maven dependence: <dependency> <groupId>com.github.qiujiawei-issac</groupId> <artifactId>light-excel-reader</artifactId> <version>1.0.0</version> </dependency> Next, we need to create an ExcelReader to read the excel file.You can create an ExcelReader object by passing the path of the Excel file or inputStream.The following is an example of creating an ExcelReader object: // Create the ExcelReader object through the file path ExcelReader reader = new ExcelReader("path/to/excel/file.xlsx"); // Or create an ExcelReader object through InputStream InputStream inputStream = new FileInputStream("path/to/excel/file.xlsx"); ExcelReader reader = new ExcelReader(inputStream); Once we get the ExcelReader object, we can use it to read the data and styles in the excel file.Next, we will focus on how to operate the styles and formats in the Excel file. 1. Set the font style of the cell To set the font style of the cell, we can use the setfont method of the ExcelReader object.The following are examples of setting the cell style of the unit grid: // Set the font style of the cell CellStyle cellStyle = reader.createCellStyle(); Font font = reader.createFont(); font.setFontName("Arial"); font.setFontHeightInPoints((short)12); cellStyle.setFont(font); // Apply the font style to the cell reader.setCellStyle(rowNum, colNum, cellStyle); 2. Set the bezel style of the cell To set up the frame style of the cell, you can use the SetBordERSTYLE method of ExcelReader object.The following is an example of setting the frame style of the unit grid: // Set the border style CellStyle cellStyle = reader.createCellStyle(); cellStyle.setBorderTop(BorderStyle.THIN); cellStyle.setBorderBottom(BorderStyle.THIN); cellStyle.setBorderLeft(BorderStyle.THIN); cellStyle.setBorderRight(BorderStyle.THIN); // Apply the frame style to the cell reader.setCellStyle(rowNum, colNum, cellStyle); 3. Set the background color of the cell To set the background color of the cell, you can use the SetFillforegroundColor method of ExcelReader.The following is an example of setting the background color of the cell: // Set background color CellStyle cellStyle = reader.createCellStyle(); cellStyle.setFillForegroundColor(IndexedColors.YELLOW.getIndex()); cellStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND); // Apply the background color to the cell reader.setCellStyle(rowNum, colNum, cellStyle); 4. Set the data format of the cell To set the data format of the cell, you can use the setdataformat method of the ExcelReader object.The following are examples of setting cell data format: // Set the data format CellStyle cellStyle = reader.createCellStyle(); DataFormat dataFormat = reader.createDataFormat(); cellStyle.setDataFormat(dataFormat.getFormat("0.00")); // Apply the data format to the cell reader.setCellStyle(rowNum, colNum, cellStyle); The above is just examples of the style and format in the Excel file. The Light Excel Reader framework provides more methods and functions to meet various needs.It is hoped that this article will help to operate the style and format in the Excel file to operate the style and format in the Excel file.
