本篇文章介绍在Java程序中将Excel表格复制然后插入到Word文档中的方法。可插入到Word中的表格包含Excel原表格的所有表格样式,如单元格背景、字符样式、单元格合并拆分、单元格对齐方式等等。
程序运行环境
编译工具:IDEA
JDK版本:1.8.0
工具Jar包:free spire.office.jar 3.9.0
测试文档格式:.xlsx/.docx 2013
具体步骤
1.在Java程序中引入jar.
这里是通过手动导入本地的jar(需事先下载jar包到本地,然后解压文件,spire.office.jar文件在文件包的lib文件夹下);另外也可以通过Maven仓库下载导入,需在pom.xml文件中配置如下内容:
<repositories>
<repository>
<id>com.e-iceblue</id>
<url>http://repo.e-iceblue.cn/repository/maven-public/</url>
</repository>
</repositories>
<dependencies>
<dependency>
<groupId>e-iceblue</groupId>
<artifactId>spire.office.free</artifactId>
<version>3.9.0</version>
</dependency>
</dependencies>
配置完成后导入。
注:这里导入jar为spire.office.jar,这个包是个集合包,在程序中需同时操作excel和word文件,须导入此jar;不能将单个的spire.doc.jar和spire.xls.jar引入Java程序,会报错。
Java代码
import com.spire.doc.Document;
import com.spire.doc.Table;
import com.spire.doc.TableCell;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.VerticalAlignment;
import com.spire.doc.fields.TextRange;
import com.spire.xls.CellRange;
import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
public class CopyExcelTableToWord {
public static void main(String[] args) {
//加载Excel 示例文档
Workbook workbook = new Workbook();
workbook.loadFromFile("test.xlsx");
//获取第一个工作表
Worksheet sheet = workbook.getWorksheets().get(0);
//复制到Word文档
copyToWord(sheet.getAllocatedRange(), "result.docx");
}
public static void copyToWord(CellRange cell, String fPath) {
//添加表格
Document doc = new Document();
Table table = doc.addSection().addTable(true);
table.resetCells(cell.getRowCount(), cell.getColumnCount());
//复制表格内容
for (int r = 1; r <= cell.getRowCount(); r++) {
for (int c = 1; c <= cell.getColumnCount(); c++) {
CellRange xCell = cell.get(r, c);
CellRange mergeArea = xCell.getMergeArea();
//合并单元格
if (mergeArea != null && mergeArea.getRow() == r && mergeArea.getColumn() == c) {
int rowIndex = mergeArea.getRow();
int columnIndex = mergeArea.getColumn();
int rowCount = mergeArea.getRowCount();
int columnCount = mergeArea.getColumnCount();
for (int m = 0; m < rowCount; m++) {
table.applyHorizontalMerge(rowIndex - 1 + m, columnIndex - 1, columnIndex + columnCount - 2);
}
table.applyVerticalMerge(columnIndex - 1, rowIndex - 1, rowIndex + rowCount - 2);
}
//复制内容
TableCell wCell = table.getRows().get(r - 1).getCells().get(c - 1);
if (!xCell.getDisplayedText().isEmpty()) {
TextRange textRange = wCell.addParagraph().appendText(xCell.getDisplayedText());
copyStyle(textRange, xCell, wCell);
} else {
wCell.getCellFormat().setBackColor(xCell.getStyle().getColor());
}
}
}
doc.saveToFile(fPath,com.spire.doc.FileFormat.Docx);
}
private static void copyStyle(TextRange wTextRange, CellRange xCell, TableCell wCell) {
//复制字体样式
wTextRange.getCharacterFormat().setTextColor(xCell.getStyle().getFont().getColor());
wTextRange.getCharacterFormat().setFontSize((float) xCell.getStyle().getFont().getSize());
wTextRange.getCharacterFormat().setFontName(xCell.getStyle().getFont().getFontName());
wTextRange.getCharacterFormat().setBold(xCell.getStyle().getFont().isBold());
wTextRange.getCharacterFormat().setItalic(xCell.getStyle().getFont().isItalic());
//复制背景色
wCell.getCellFormat().setBackColor(xCell.getStyle().getColor());
//复制排列方式
switch (xCell.getHorizontalAlignment()) {
case Left:
wTextRange.getOwnerParagraph().getFormat().setHorizontalAlignment(HorizontalAlignment.Left);
break;
case Center:
wTextRange.getOwnerParagraph().getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
break;
case Right:
wTextRange.getOwnerParagraph().getFormat().setHorizontalAlignment(HorizontalAlignment.Right);
break;
default:
break;
}
switch (xCell.getVerticalAlignment()) {
case Bottom:
wCell.getCellFormat().setVerticalAlignment(VerticalAlignment.Bottom);
break;
case Center:
wCell.getCellFormat().setVerticalAlignment(VerticalAlignment.Middle);
break;
case Top:
wCell.getCellFormat().setVerticalAlignment(VerticalAlignment.Top);
break;
default:
break;
}
}
}
执行程序后,生成Word结果文档。以上代码中的文件路径为IDEA项目程序运行路径,如本次路径F:\IDEAproject\CopyExcelTableToWord_Office\result.docx,文件路径可另行自定义。
测试的Excel源文档如图:
Word结果文档如图效果:
