The grid can be configured to allow simple text selection.
Enabling Cell Text Selection
To enable text selection as if the grid were a regular table, set the grid option enableCellTextSelection = true. For the selection to work correctly, the order of the rows within the DOM must much what is displayed by setting the grid option ensureDomOrder = true.
When enableCellTextSelection is set to true, the default Clipboard behaviour is disabled, and only the selected text is copied.
