Alternate Dimension wont work in Simple Table.
Try using a Extension (https://www.quickintelligence.co.uk/toggle-buttons-qlik-sense/ or Makes Sense to go round in circles)
These both tutorials will help you to change dimension in chart using Variables.. It will look like a Alternate Dimension
Suppose you have 2 dimension : Name and Post
and u want to have a choice to show one of them (or maybe both)
do as follow:
create an inline table in ur script:
Load * inline [
Now add this new Dimension as a filter above ur table.
And within ur table, as a dimension create:
for Its label : Dimension
and now you have a sort of 'alternative dimensions' in ur straight table.
Please, download this extension:
and use it as a filter for ur newly created Dimension.
In the option do as follow to force a selection of only one value and have a by default selected value:
result (per analogy):
Hope this helps !
