Grid copy & paste

In dhtmlx 5, dhtmlxGrid.enableBlockSelection(true), dhtmlxGrid.setCSVDelimiter(’\t’), dhtmlxGrid.copyBlockToClipboard(), dhtmlxGrid.pasteBlockFromClipboard() These functions were used to copy & paste from Excel to Grid.
Is it possible to implement in dhtmlx 7 ?
If possible, I would like to receive an example source.

There is no copy-paste functionality in grid 7. In this case, you may try to use the dhx.Spreadsheet widget:

Thank you for answer.
Is it impossible to implement the function without using the dhx.Spreadsheet widget ?

There is no block selection or the functionality to operate with the clipboard in the dhx.Grid 7.
