+// TableView interprets UART lines as delimited data and shows them in a table.
+// The first line that matches the column count is used as the header row if it
+// starts with '#'. Otherwise column names are auto-generated (Col 1, Col 2, …).
+//
+// Supported delimiters: comma, semicolon, tab, pipe, space
+// To use: send lines like:
+//   #time,temp,voltage,current
+//   1234,23.5,3.3,0.42
