apache poi绘制边界

本文概述

• Apache POI绘图边框示例

Apache POI允许我们在工作簿工作表中应用一组边界。 PropertyTemplate对象使用定义为允许绘制单元格的顶部，底部，左侧，左侧，右侧，水平，垂直，内部，外部边界的方法和常量对此进行模拟。

让我们看一个示例，其中我们在单元格周围绘制边框。

package poiexample;
import java.io.FileOutputStream;
import java.io.OutputStream;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.ss.usermodel.BorderExtent;
import org.apache.poi.ss.usermodel.BorderStyle;
import org.apache.poi.ss.usermodel.IndexedColors;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.util.CellRangeAddress;
import org.apache.poi.ss.util.PropertyTemplate;
public class DrawingBorderExample {
	public static void main(String[] args) {		
		try (OutputStream os = new FileOutputStream("srcmini.xls")) {	
			 PropertyTemplate pt = new PropertyTemplate();
			 pt.drawBorders(new CellRangeAddress(1, 2, 1, 2), BorderStyle.MEDIUM, BorderExtent.ALL);
			 pt.drawBorders(new CellRangeAddress(5, 6, 1, 2), BorderStyle.MEDIUM, BorderExtent.OUTSIDE);
			 pt.drawBorders(new CellRangeAddress(5, 6, 1, 2), BorderStyle.THIN, BorderExtent.INSIDE);
			 pt.drawBorders(new CellRangeAddress(9, 10, 1, 3), BorderStyle.MEDIUM, IndexedColors.GREEN.getIndex(), BorderExtent.OUTSIDE);
			 pt.drawBorders(new CellRangeAddress(9, 10, 1, 3), BorderStyle.MEDIUM, IndexedColors.BLUE.getIndex(), BorderExtent.INSIDE_VERTICAL);
			 pt.drawBorders(new CellRangeAddress(9, 10, 1, 3), BorderStyle.MEDIUM, IndexedColors.RED.getIndex(), BorderExtent.INSIDE_HORIZONTAL);
			 pt.drawBorders(new CellRangeAddress(10, 10, 2, 2), BorderStyle.NONE, BorderExtent.ALL);
			 Workbook wb = new HSSFWorkbook();
			 Sheet sheet = wb.createSheet("Sheet");
			 pt.applyBorders(sheet);
			 wb.write(os);
		}catch(Exception e) {
			System.out.println(e.getMessage());
		}
	}
}
