In Microsoft Word, it is possible to use very simple formula e.g. =SUM(ABOVE)
to display the total of a column or =SUM(LEFT)
etc. Is it possible to do something similar in Google Docs? Obviously this is possible in Google Spreadsheets, but I need to do it within a table in a document.

Best Answer
At this time Google Docs (documents) doesn't include a feature to do calculations.
An alternative is to use an add-on or a Google Apps Script to extend the built-in features of Google Docs.
