How to filter/remove columns in Tableau when there is no data

Question

Trying to create a longish timeseries of trends in A-level results over past three years.

Two problems. I can't find any options to remove the columns in visualisation where there is no data such as 2019 or 2023.

Answer 1

Edit: I just changed the data type of "Year" into date and dragged it to the columns pane. now the values range between 2020 to 2022
