可以通过打开 convertSheetTableToDataTable 选项，将所有工作表表格转换为绑定到数据管理器的数据表，并通过打开 GC.Spread.Sheets.ExportXlsxOptions 的 includeBindingSource 选项导出到 Excel 文件。需要注意的是，导入或导出时列基公式会被转换，导入时单元格基公式会被移除。
window.onload = () => {
let spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"));
initSpread(spread);
};
async function initSpread(spread) {
const loadingTip = addLoadingTip();
const tableImportExcel = document.getElementById('options-container');
await tableImportExcel.setSpread(spread);
loadingTip.remove();
}
