有时，您需要在电子表格中隐藏零值。这可能是个人偏好或格式化标准。
要在Microsoft Excel中隐藏工作表中的零值（例如Microsoft Excel 2003）：
- 从工具菜单中选择选项，然后选择视图选项卡。
- 取消选中零值选项。
- 点击确定。
请参阅以下示例代码，演示如何使用 C++ 的 Aspose.Cells for JavaScript 隐藏零值。

return;
}
const file = fileInput.files[0];
const arrayBuffer = await file.arrayBuffer();
// Instantiating a Workbook object from uploaded file
const workbook = new Workbook(new Uint8Array(arrayBuffer));
// Get First worksheet of the workbook
const sheet = workbook.worksheets.get(0);
// Hide the zero values in the sheet
sheet.displayZeros = false;
// Save the 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 = 'outputfile.out.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>';
