使用 JavaScript 通过 C++ 创建联合范围

创建联合范围

Aspose.Cells 提供通过 WorksheetCollection.createUnionRange 方法创建联合范围的能力。该方法接受两个参数：用于创建联合范围的地址和工作表的索引。该方法返回一个 UnionRange 对象。

以下代码片段演示了如何使用 WorksheetCollection.createUnionRange 方法创建联合范围。生成的输出文件已附上供参考。

输出文件

    <body>
        <h1>Create Union Range Example</h1>
        <input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
        <button id="runExample">Run Example</button>
        <a id="downloadLink" style="display: none;">Download Result</a>

    <script src="aspose.cells.js.min.js"></script>
    <script type="text/javascript">
        const { Workbook, SaveFormat } = AsposeCells;

        AsposeCells.onReady({
            license: "/lic/aspose.cells.enc",
            fontPath: "/fonts/",
            fontList: [

            ]
        }).then(() => {
            console.log("Aspose.Cells initialized");
        });

        document.getElementById('runExample').addEventListener('click', async () => {
            const fileInput = document.getElementById('fileInput');
            if (!fileInput.files.length) {
                document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
                return;
            }

            const file = fileInput.files[0];
            const arrayBuffer = await file.arrayBuffer();

            // Instantiating a Workbook object from the uploaded file
            const workbook = new Workbook(new Uint8Array(arrayBuffer));

            // Create union range
            const unionRange = workbook.worksheets.createUnionRange("sheet1!A1:A10,sheet1!C1:C10", 0);

            // Put value "ABCD" in the range (converted setter to property)
            unionRange.value = "ABCD";

            // Save the output workbook and provide a download link
            const outputData = workbook.save(SaveFormat.Xlsx);
            const blob = new Blob([outputData]);
            const downloadLink = document.getElementById('downloadLink');
            downloadLink.href = URL.createObjectURL(blob);
            downloadLink.download = 'CreateUnionRange_out.xlsx';
            downloadLink.style.display = 'block';
            downloadLink.textContent = 'Download Excel File';

            document.getElementById('result').innerHTML = '<p style="color: green;">Union range created successfully! Click the download link to get the modified file.</p>';
        });
