If you try to copy a list and then paste it into a table (in Google Docs) it pastes everything into the same cell rather than pasting each item in every row/column.
Quick Workaround.
- Copy the list of items
- Open a new google spreadsheet (use sheets.new short URL) or a dummy sheet
- Paste the contents to the sheet
- Again copy from the sheet
- Now, paste them into the table.
Until Google adds a feature for this, use this workaround.
