对于列名称带空格的 SharePoint、Excel 或 Power BI 磁贴之类的数据源,Power Apps 会将空格替换为"_x0020_"。 例如,如果 SharePoint、Excel 或 Power BI 磁贴中的Column Name在数据布局中显示或用于公式,它将在 Power Apps 中显示为Column_x0020_Name。
注意 如果資料來源 (如 SharePoint、Excel 或 Power BI 圖標) 包含有空格的資料行名稱,Power Apps 會將空格取代為 "_x0020_"。 例如,SharePoint、Excel 或 Power BI 圖標中的資料行名稱在資料版面配置中顯示或是在公式中使用時,會在 Power Apps 中顯示為 "Column_x0020_Name"。
