I quite like: first cell second cell last cell second line where the large spaces are tab characters. Which can be expressed in a eText rule much like: Table: make object! [ Type: 'TH Mark: #"|" NonBar: exclude Printable charset to-string Mark Cells: make block! 10 BarCell: [Mark Align copy Line some NonBar] TabCell: [copy Line some Printable Line] Append-Cell: does [ repend Cells [make path! reduce [Type Align!/Type] Inline Line] ] Row: [ [ [ opt [some [Mark some #"-"] opt Mark newline] some [BarCell (Append-Cell)] opt Mark ] | Align TabCell (Append-Cell) some [ tab Align TabCell (Append-Cell) ] ] newline ] Rows: make block! 10 Rule: [ opt Empty ( Type: 'TH Rows: make block! 10 Cells: make block! 10 ) some [ Row ( repend Rows ['TR Cells] Type: 'TD Cells: make block! 10 ) ]( repend Block ['Table Rows] ) ] ] and seems to work quite well for me.
