What is filtering data in a table?

To display a subset of the items in a table, define filter rules that show only the items in which you are interested. Filtering does not refresh the table; therefore, you are filtering only the items currently listed in the table.

What is filtering in data visualization?

Data filtering is the process of choosing a smaller part of your data set and using that subset for viewing or analysis. Filtering is generally (but not always) temporary – the complete data set is kept, but only part of it is used for the calculation.
