在extjs中有条件地在网格中显示/隐藏列

Question

I have grid in my application, I need to show/hide particular column conditionally. Please help me.

Code:

{
    header: 'Type',  dataIndex: 'mirror',  flex: 1, sortable: true,
    renderer: function (value, meta, record, rowIndex, colIndex, store) {
                    if(value == '')
                        return "-";
                    else
                        return value;
            }
}

currently it shows - incase no records,but I need to remove column incase no record found.

Columns have a hide method which you can use. For example, take a look at this example that show you how to hide an specific column in runtime.

If you want to hide/show a the column depending on a condition, you have to evaluate that condition and use the hide & show methods.
