可能的使用场景
当单元格含文本或字符串，但其长度超过单元格宽度时，如果下一列的单元格为空，字符串会溢出。保存Excel为HTML时，可以通过指定交叉类型（HtmlCrossType枚举）控制此溢出。其值包括：
-
HtmlCrossType.Default：显示方式类似MS Excel；依赖下一单元格。如果下一单元格为空，字符串将会超出或被截断。
-
HtmlCrossType.MSExport: 以MS Excel导出HTML的方式显示字符串.
-
HtmlCrossType.Cross：显示 HTML 交叉字符串；创建大型 HTML 文件的性能比设置为 Default 或 FitToCell 快十倍以上。
-
HtmlCrossType.FitToCell：仅在单元格宽度内显示字符串。
使用HtmlCrossType指定输出HTML中如何交叉字符串
以下示例代码加载示例Excel文件，并通过指定不同的HtmlCrossType将其保存为HTML格式。请下载由此代码生成的输出HTML。示例Excel文件包含一个以红色边框标记的图片，如此截图所示，展示了HtmlCrossType值对输出HTML的影响。
示例代码
<!DOCTYPE html>
<html>
<head>
<title>Aspose.Cells Example</title>
</head>
<body>
<h1>Export HTML Cross String Type 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, HtmlSaveOptions, HtmlCrossType, Utils } = 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();
// Instantiating a Workbook object from the uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Specify HTML Cross Type via HtmlSaveOptions
const opts = new HtmlSaveOptions();
// Applying the sequence of assignments as in the original JavaScript code
opts.htmlCrossStringType = HtmlCrossType.Default;
opts.htmlCrossStringType = HtmlCrossType.MSExport;
opts.htmlCrossStringType = HtmlCrossType.Cross;
opts.htmlCrossStringType = HtmlCrossType.FitToCell;
// Save workbook to HTML using the specified options
const outputData = workbook.save(SaveFormat.Html, opts);
const blob = new Blob([outputData], { type: "text/html" });
const downloadLink = document.getElementById('downloadLink');
const fileName = 'out' + opts.htmlCrossStringType + '.htm';
downloadLink.href = URL.createObjectURL(blob);
downloadLink.download = fileName;
downloadLink.style.display = 'block';
downloadLink.textContent = 'Download HTML File';
document.getElementById('result').innerHTML = '<p style="color: green;">HTML exported successfully! Click the download link to get the file.</p>';
