可能的使用场景
不同的Excel格式支持不同的行和列。例如，XLS支持65536行和256列，而XLSX支持1048576行和16384列。若想知道某一格式支持多少行列，可使用 WorkbookSettings.maxRow 和 WorkbookSettings.maxColumn 属性。
查找XLS和XLSX格式支持的最大行数和列数
以下示例代码先创建XLS格式的工作簿，再创建XLSX格式的工作簿，之后输出 WorkbookSettings.maxRow 和 WorkbookSettings.maxColumn 属性的值。请参考以下控制台输出。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Maximum Rows and Columns Example</h1>
<input type="file" id="fileInput" accept=".xls,.xlsx,.csv" />
<button id="runExample" disabled>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, Utils } = AsposeCells;
const runBtn = document.getElementById('runExample');
const resultDiv = document.getElementById('result');
AsposeCells.onReady({
license: "/lic/aspose.cells.enc",
fontPath: "/fonts/",
fontList: [
"arial.ttf",
"NotoSansSC-Regular.ttf"
]
}).then(() => {
console.log("Aspose.Cells initialized");
runBtn.disabled = false;
});
runBtn.addEventListener('click', async () => {
// Print message about XLS format.
resultDiv.innerHTML = '<p>Maximum Rows and Columns supported by XLS format.</p>';
// Create workbook in XLS format.
let wb = new Workbook(AsposeCells.FileFormatType.Excel97To2003);
// Print the maximum rows and columns supported by XLS format.
let maxRows = wb.settings.maxRow + 1;
let maxCols = wb.settings.maxColumn + 1;
resultDiv.innerHTML += `<p>Maximum Rows: ${maxRows}</p>`;
resultDiv.innerHTML += `<p>Maximum Columns: ${maxCols}</p>`;
resultDiv.innerHTML += '<hr/>';
// Print message about XLSX format.
resultDiv.innerHTML += '<p>Maximum Rows and Columns supported by XLSX format.</p>';
// Create workbook in XLSX format.
wb = new Workbook(AsposeCells.FileFormatType.Xlsx);
// Print the maximum rows and columns supported by XLSX format.
maxRows = wb.settings.maxRow + 1;
maxCols = wb.settings.maxColumn + 1;
resultDiv.innerHTML += `<p>Maximum Rows: ${maxRows}</p>`;
resultDiv.innerHTML += `<p>Maximum Columns: ${maxCols}</p>`;
});
</script>
</html>
控制台输出
Maximum Rows and Columns supported by XLS format.
Maximum Rows: 65536
Maximum Columns: 256
Maximum Rows and Columns supported by XLSX format.
Maximum Rows: 1048576
Maximum Columns: 16384
