I'm colorizing the header of a table formatted with column -ts $'\t'Works well without color codes, but when I add color codes to the first line column doesn't properly align the output.Without colored output it works as expected:printf 1\t2\t3\nasdasdasdasdasdasdasd\tqwe\tqweqwe\n | column -ts $'\t'But when adding color on the first line column doesn't align the text of the colored row:printf \e[7m1\t2\t3\e[0m\nasdasdasdasdasdasdasd\tqwe\tqweqwe\n | column -ts $'\t'Observed this behaviour both on Ubuntu Linux and Mac OS X.
Issue with column command and color escape codes
colors;escape characters;columns;text formatting;table
I imagine that column doesn't know that \e[7m is a v100 escape sequence that takes no space in the output. It seems to asssume character codes 0 to 037 octal take no space. You can get what you want by putting the initial escape sequence on a line of its own, then removing that newline from the output:printf '\e[7m\n1\t2\t3\e[0m\nasdasdasdasdasdasdasd\tqwe\tqweqwe\n' | column -ts $'\t' |sed '1{N;s/\n//}'
