读取和写入带有查询表数据源的表格
使用Aspose.Cells for Node.js via C++,可以读取和写入具有QueryTable作为数据源的表。此功能也支持XLS文件。以下代码演示读取和写入此类表,先读取表格,再进行修改以添加合计行。
const path = require("path");
const AsposeCells = require("aspose.cells.node");
// The path to the source directory.
const sourceDir = path.join(__dirname, "data");
const outputDir = path.join(__dirname, "output");
// Load workbook object
const workbook = new AsposeCells.Workbook(path.join(sourceDir, "SampleTableWithQueryTable.xls"));
const worksheet = workbook.getWorksheets().get(0);
const table = worksheet.getListObjects().get(0);
// Check the data source type if it is query table
if (table.getDataSourceType() === AsposeCells.TableDataSourceType.QueryTable) {
table.setShowTotals(true);
}
// Save the file
workbook.save(path.join(outputDir, "SampleTableWithQueryTable_out.xls"));
源和输出的Excel文件已附上供参考。
