Markdown table syntax
| Left | Center | Right | | :----- | :----: | ----: | | a | b | c |
A colon on the left of the dashes aligns a column left, on both sides centres it, and on the right aligns it right. You need at least three dashes per column, and every row needs the same number of cells.
Getting tables out of other places
| From | How |
|---|---|
| Excel, Numbers, Google Sheets | Select cells, ⌘C, paste above |
| A CSV file | Open it in a text editor, copy all, paste above |
| A web page | Select the table, copy, paste into a spreadsheet first, then here |
| A PDF or screenshot | Use Pastely: it reads the table from the image |
