Apache POI允许无涯教程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(top),底部(bottom),左侧(left),右侧(right),水平(horizontal),垂直(vertical),内部(inside),外部(outside)边界的方法和常量对此进行模拟。
看一个示例,其中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("Learnfk.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()); } } }
输出:
