调用 setRowCount 和 setColumnCount 方法来改变表单区域的行数和列数。 此外, 你可以调用 addRows, addColumns, deleteRows, 和 deleteColumns 方法来改变视图区域的行列数。
当调用setRowCount和setColumnCount方法时，你可以选择保护哪个使用的范围类型。
以下代码可以用来改变表单视图区域的行与列。
如果行或者列的 resizeable 属性为 false , 那么将不能通过 UI 行为改变行列大小, 但是你仍可以通过执行代码来直接改变他们的高宽。
调用 setRowVisible 和 setColumnVisible 方法来指定行列是否可见。
在表单的视图区域, 当行或者列是自动匹配高宽, 它的内容将决定他的高度或者宽度。通过以下代码来设置一行或一列自动匹配高宽:
SpreadJS 也提供了很多接口来获取表单行和列的详细信息, 例如以下代码:
SpreadJS 提供 resizeZeroIndicator 方法来控制当行高或列宽为0时，是否在行头或列头上显示双线提示线。参数为 ResizeZeroIndicator 枚举值。
default: 单线 (与正常显示相同)
enhanced: 双线提示线 (默认值)
