.h2 DbGrid

A database grid widget that displays all records from a Data control in a scrollable, sortable table. Columns auto-populate from the Data control's column names and can be hidden, resized, and renamed by the application. Clicking a column header sorts the display. Selecting a row syncs the Data control's cursor position. The grid reads directly from the Data control's cached rows, so there is no separate copy of the data.
