Apr 19, 2025 pm 08:39 PMCreate Excel tables and set cell borders using Java and GrapeCity Documents for Java components
Many Java developers need to add various styles of borders to cells when creating Excel files. This article will demonstrate how to use GrapeCity Documents for Java components (rather than Apache POI) to implement this functionality efficiently, especially creating complex border styles as shown in the image above.
The following code snippet shows how to create a workbook and set different types of borders (solid, dotted, dashed, double lines, etc.) for the "B2:E6" area, as well as different colors:
/* https://demo.grapecity.com.cn/documents-api-excel-java/demos/ addborderstorange?devLang=java */ // Create a workbook Workbook = new Workbook(); IWorksheet worksheet = workbook.getWorksheets().get(0); IRange rangeB2_E6 = worksheet.getRange("B2:E6"); // Set the outer border style and color rangeB2_E6.getBorders().setLineStyle(BorderLineStyle.DashDot); rangeB2_E6.getBorders().setColor(Color.GetGreen()); // Set the internal horizontal border rangeB2_E6.getBorders().get(BordersIndex.InsideHorizontal).setLineStyle(BorderLineStyle.Dashed); rangeB2_E6.getBorders().get(BordersIndex.InsideHorizontal).setColor(Color.GetTomato()); // Set the internal vertical border rangeB2_E6.getBorders().get(BordersIndex.InsideVertical).setLineStyle(BorderLineStyle.Double); rangeB2_E6.getBorders().get(BordersIndex.InsideVertical).setColor(Color.GetBlue()); // Set the top border separately rangeB2_E6.getBorders().get(BordersIndex.EdgeTop).setLineStyle(BorderLineStyle.Medium); rangeB2_E6.getBorders().get(BordersIndex.EdgeTop).setColor(Color.GetRed()); // Save Excel file workbook.save("AddingBordersToRange.xlsx");
This code first creates a workbook and worksheet, and then selects the "B2:E6" area. After that, the line shape and color of the outer border of the area and the inner horizontal and vertical borders are set respectively. Finally, save the result as the "AddingBordersToRange.xlsx" file. This method flexibly controls cell border styles to meet various complex typesetting needs. Note that this code uses GrapeCity Documents for Java, not Apache POI. To use Apache POI to implement similar functions, please refer to its API documentation.

User voice input is captured and sent to the PHP backend through the MediaRecorder API of the front-end JavaScript; 2. PHP saves the audio as a temporary file and calls STTAPI (such as Google or Baidu voice recognition) to convert it into text; 3.

To allow PHP services to pass through the Windows 11 firewall, you need to create inbound rules to open the corresponding port or program. 1. Determine the port that PHP is actually listening. If the built-in server is started with php-Slocalhost:8000, the port is 8000. If using Apache or IIS, it is usually 80 or 443. 2. Open the advanced settings of "WindowsDefender Firewall", create a new inbound rule, select "Program" or "Port", fill in the PHP or Web server path or specify the port number. 3. Select Allow Connections, check the applicable network configuration file, name the rules and add a description. The IP addresses that are allowed to access, such as local network or specific IP, can be restricted through the scope. Safety
