Column aggregation functions may be enabled independently of group aggregation functions. Every group aggregation function, except <em>Filter rows (by regexp)</em>, requires exactly <strong>one</strong> field to be assigned the <em>Group and compress</em> function. With that done, select any of the other aggregation functions for some or all of the fields. Functions marked with an asterisk take an optional parameter. For the aggregation functions <em>Enumerate, Range</em> and <em>Tally</em> the optional parameter is a delimiter to separate items. <br/>If you rewrite the results of a field, the aggregation functions will still use the original value. You can use a Global:Custom text field and Twig syntax instead to rewrite the results and apply aggregation functions on it. The Twig number_format() filter can be applied as last filter, its settings for decimal and thousand separator will be respected by the aggregation functions.<br/>You may combine multiple fields into the same render column. If you do, the separator specified will be used to separate the fields. You can control column order and field labels in the Fields section of the main configuration page.
