推荐答案

您不想使用隐藏属性，你真的想选择列，右单击并选择列能见度。一旦在这里你可以使用一个前pression基于参数设置的知名度，是这样的：

You don't want to use the Hidden property, you actually want to select the column, Right Click and select Column Visibility. Once in here you can use an expression to set the visibility based on a parameter, something like this:

= iif(Parameters!column_visible.Value = 1, false, true)

隐藏不会在这种情况下工作，因为你没有真正把它应用到一个对象像你，当你选择像一个文本框。

Hidden doesn't work in this instance because you're not actually applying it to an object like you are when you select something like a textbox.
