Why does the automatic mode choose two spaces?

In aligned terminal output a single space can appear inside a value, while two or more spaces are the gap between columns. Splitting on two spaces keeps names with one space intact, and any-run-of-spaces is available when a column is narrow.

What happens to a pipe in the data?

In a Markdown table a pipe would end the cell, so it is escaped as a backslash followed by the pipe. In CSV and TSV output the usual quoting rules apply instead.

Can I drop the header?

Clear the first-row box and the table is written without one. In Markdown output that means generic column names are used, because the format expects a header line.

How the columns are separated Output

First row is the header Trim whitespace

Output

Works on the aligned columns of docker ps, ps, df, kubectl and anything else that lines up in a terminal. Short rows are padded, so the table always comes out rectangular.

About this tool

Turn the columns printed by docker ps, ps, df or kubectl into a table you can paste into a document or a ticket. The separator is detected from the text, and the output can be a Markdown table, CSV or TSV. Rows of different lengths are padded so the result is always rectangular.
