Introduction
Show/Hide 
is a feature used to hide certain columns or headers of the selected report. Here were are going to explain how this feature is used in different datablocks.
Cube Report
In a cube report usually the report is in form of chart. If we want to display it in grid mode then comes the feature for Show/Hide columns. It gives user option to display the desired columns as well as column headers. As in the screenshot below we can see we have two options at the top 1. Select/Deselect All (Here we can select r deselect all the columns) and 2. Show Column Headers (by default this is checked but if we don't want to display column headers then this option needs to be unchecked. We also have option to sort our columns. On the left hand side all column names are displayed in alphabetical order and on the right they are ordered as they are displayed in grid. In case we wish to change the order of display in grid we can simply drag the column name from left to right on the position where we want it to be displayed. e.g. In the screenshot below we wanted 'Hour' to be displayed at the top so we dragged it from left to right at the top-most position and in this process it pushed the 1st position column to the 2nd position.
