主题：为什么产品查询表中会多一空白行呢，删除了，保存后还是会显示出来

你的公式delfor有问题，这样试试：
ClearGrid(GridName) and AppendFor("产品录入窗口","Article Description,Code number","Article Description,Code number","Article Description"," = ",[%Article Description%]) and FilterFor("Article Description","=",[%Article Description%]) and delfor(grid,"Article Description"," = ","") And FilterRGrid(GridName) And FilterRGrid(GridName,"Article Description","=",[%Article Description%])
