Pasted Data
Copy rows from a spreadsheet or a text file, click an empty part of the canvas, and paste. Mycorr detects whether the text is tab- or comma-separated and creates a new table from it.
If a single cell is selected when you paste, the text goes into that cell instead of making a new table.
A pasted table is owned by the model, like an uploaded one: anyone who can edit the model can edit it.
