I have a calculation and it outputs multiple values. Then I am creating a table on those values. For example, in below data my formula is
if data is 1 then calculation is `one`
if data is 2 then calculation is `two`
if data is 3 then calculation is `three`
as three
doesn't really appear in the output, when I create a table, three
is not displayed. Is there any way to display it? I tried table layout >> show empty rows and columns
and it didn't work
data calculation
1 one
2 two
Tableau discovers the possible values for a dimension field dynamically from the query results.
If 'three' does not appear in your data, then how do you expect Tableau to know to make a column header for that non existent, but potential, value? It can't read your mind.
This situation does occur often though - perhaps you want row or column headers to remain stable, even when you change filters in a way that causes some to no longer appear in the query results.
There are a few ways you can force Tableau to pad ** or **complete a domain:
You can often do this easily by using a union to append some extra rows to your original data. You can often add padding rows that don't impact any results by leaving all your Measure columns null since nulls are ignored by aggregation functions
There are two situations where Tableau can detect the absence of data and leave space for it in the visualization automatically
for numeric types, you can create a bin field that will automatically pad for missing bins
similarly, date fields can show missing values because, like bins, Tableau can tell when a month doesn't appear in the data and leave room for it in the view
