Group Footer Cell
- 2 minutes to read
A node‘s group footer cell displays a group summary calculated against a column‘s values corresponding to this node.
Normally, one group footer cell is displayed per each summary item specified for a column. In a stacked column layout, a single group footer cell is shown per column, and the cell displays all summaries separated by a character.
The position and size of group, footer, and data cells are determined by the column header layout. Users can adjust a cell’s width and make it span across multiple lines.
Group footer cells are similar to footer cells, except for the position and HitTest information.
