紹介
Excelでは、範囲を選択して削除し、他のデータを左にシフトすることができます。
Aspose.Cells for JavaScriptを用いた範囲削除
Aspose.CellsはCells.deleteRange(数値, 数値, 数値, 数値, ShiftType)メソッドを提供し、範囲を削除します。
範囲の削除と左にセルをシフト
次のコード例を使用して範囲を削除し、セルを左にシフトします（Aspose.Cells for JavaScriptをC++で使用）：
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Aspose.Cells 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>
<div id="result"></div>
</body>
<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: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
document.getElementById('runExample').addEventListener('click', async () => {
const fileInput = document.getElementById('fileInput');
const resultDiv = document.getElementById('result');
if (!fileInput.files.length) {
resultDiv.innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Loads the workbook which contains hidden external links (from uploaded file)
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Instantiate a new Workbook.
const newWorkbook = new Workbook();
// Get all the worksheets in the book.
const worksheets = newWorkbook.worksheets;
// Get the first worksheet in the worksheets collection.
const worksheet = newWorkbook.worksheets.get(0);
// Gets cells.
const cells = worksheet.cells;
// Input some data with some formattings into a few cells in the range.
cells.get("C2").value = "C2";
cells.get("C3").value = "C3";
const ca = AsposeCells.CellArea.createCellArea("B2", "B3");
cells.deleteRange(ca.startRow, ca.startColumn, ca.endRow, ca.endColumn, AsposeCells.ShiftType.Left);
const check = worksheet.cells.get("B2").stringValue === "C2";
// Save the modified newWorkbook and provide download link
const outputData = newWorkbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData]);
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
resultDiv.innerHTML = `<p style="color: green;">Operation completed successfully! Check result: ${check}</p>`;
});
});
</script>

範囲の削除と上にセルをシフト
次のコード例を使用して範囲を削除し、セルを上にシフトします（Aspose.Cells for JavaScriptをC++で使用）：

<a id="downloadLink" style="display: none;">Download Result</a>
<div id="result"></div>
</body>
<script src="aspose.cells.js.min.js"></script>
<script type="text/javascript">

cellB5.value = "B5";
const ca = AsposeCells.CellArea.createCellArea("B2", "B3");
cells.deleteRange(ca.startRow, ca.startColumn, ca.endRow, ca.endColumn, AsposeCells.ShiftType.Up);
const check = cells.get("B2").stringValue === "B4";
console.log(check);
