The lowest level of the split is specified through the Child Split column. The horizons into which that horizon merges are specified (in the order of merging) through the Merge Horizons columns.
The panel utilises grid controls to manage the grid information, i.e. right-click context menus, that allow you to perform options such as hiding columns, cutting, copying, and pasting cells, and inserting and deleting rows. Right-click in the grid area to display the context menu. Descriptions of the available options are listed below.
