紹介
この記事では、大規模なデータセットを操作する際に、同じワークシートの異なる部分を比較するために、2つまたは4つに分割して表示する方法を学びます。分割表示機能はあなたのニーズに応えます。
Excelで画面を分割する方法
ワークシートを2つまたは4つの部分に分割するには、次のようにします:
- 分割を配置したい行/列/セルを選択します。
- [表示]タブの[ウィンドウ]グループで、[分割]ボタンをクリックします。

列単位でワークシートを分割
スプレッドシートの2つの領域を垂直に分割するには、分割を表示したい列の右側の列を選択し、Excelの[分割]ボタンをクリックします。
C++を用いたAspose.Cells for JavaScriptでワークシートを垂直に分割することは簡単です。最上部の行のいずれかのセルをアクティブセルとして選択し、Worksheet.split()メソッドで分割します。

const fileInput = document.getElementById('fileInput');
if (!fileInput.files.length) {
document.getElementById('result').innerHTML = '<p style="color: red;">Please select an Excel file.</p>';
return;
}
await readyPromise;
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiate a new Workbook from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access the first worksheet
const sheet = workbook.worksheets.get(0);
// Sets C1 cell in the top row as the active cell.
sheet.activeCell = "C1";
// Split worksheet vertically on columns
sheet.split();
// Save the modified workbook and prepare 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 = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Worksheet updated successfully! Click the download link to get the modified file.</p>';
});
</script>

行単位でワークシートを分割
Excelウィンドウを水平に分割するには、Excelで分割が発生する行の下の行を選択します。
C++を用いたAspose.Cells for JavaScriptで、左列のセルをアクティブにして横方向にワークシートを分割するのは簡単です。

<h1>Aspose.Cells Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />

}).then(() => {

});
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));
// Accessing the first worksheet in the Excel file
const sheet = workbook.worksheets.get(0);
// Sets A6 cell in the left column as the active cell.
sheet.activeCell = "A6";
// Split worksheet horizontally on rows
sheet.split();
// Saving the modified Excel file
const outputData = workbook.save(SaveFormat.Xlsx);
const blob = new Blob([outputData], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' });
const downloadLink = document.getElementById('downloadLink');
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = 'dest.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Operation completed successfully! Click the download link to get the modified file.</p>';
});
</script>

ワークシートを4つの部分に分割する
同じワークシートの4つの異なるセクションを同時に表示するには、Excelで画面を縦横に分割します。
C++を使ったAspose.Cells for JavaScriptで、最初の行と列以外のセルをアクティブに選択し、縦にワークシートを分割するのは簡単です。
<!DOCTYPE html>
<html>
<head>
<title>Set Active Cell and Split Worksheet Example</title>
</head>
<body>
<h1>Set Active Cell and Split Worksheet 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');
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();
// Instantiate a new Workbook from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Access the first worksheet
const sheet = workbook.worksheets.get(0);
// Sets E6 cell as the active cell.
sheet.activeCell = "E6";
// Split worksheet into four parts
sheet.split();
// Save the modified 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 = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Worksheet updated successfully. Click the download link to get the modified file.</p>';
});
</script>
</html>
分割を削除する方法
ワークシートの分割を解除するには、再び分割ボタンをクリックします。
C++のAspose.Cells for JavaScriptは、分割設定を解除するためのWorksheet.removeSplit()メソッドを提供します。
<!DOCTYPE html>

<body>
<h1>Split Worksheet 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({

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();
// Instantiate a new Workbook from uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
const sheet = workbook.worksheets.get(0);
// Remove split and then split worksheet into four parts
sheet.removeSplit();
sheet.split();
// Save the modified workbook and provide 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 = 'output.xlsx';
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download Modified Excel File';
document.getElementById('result').innerHTML = '<p style="color: green;">Worksheet split operation completed successfully! Click the download link to get the modified file.</p>';
});
