Hover over any field header and click the arrow icon that appears to show the field header menu. You will see the name of the field and the data type of its values. The icons at the top of the menu allow you to perform the following actions:
Highlight the field. You can also do this by clicking the field header.
Expand or shrink the field to the default size. You can also adjust the size of the fields by dragging the top right side of the header. Learn more.
Hide the field. To display it again, select Field → Show hidden fields on the toolbar. Hide and show fields.
The menu also shows the top 10 distinct values with the highest number of instances in the field.
Missing values
This list shows only the data that has been loaded in the browser so far and corresponds to the percentage indicated in the Event loading indicator (more info on the Event loading indicator in tab 3). Due to this, note that you may not see some of the values in your query when you use the search box to filter the list. Filter the data in the table if you want to verify that the values you are looking for exist or not.
