Every now and again there is a question in the community “How to drag new rows like in Excel”.
The short answer is that Coda does not provide that functionality. Simple drag and drop is sacrificed for much better functionality around row and table management.
But this being Coda, there is always ways to make things better. In reply to a community question, I created two examples on the page below. One is to create new rows, filled with values from a counter. The second is simply copies a value(s) to new rows.
Very simple, but can sometimes be helpful.
It’s just a ramble,
