 Tablizer  can   be  used   to  re-format   tabular  output   of  other
 programs. While you  could do this using standard unix  tools, in some
-cases it's a hard job. With tablizer you can filter by column[s],
-ignore certain column[s] by regex, name or number. It can output the
-tabular data in a range of formats (see below). There's even an
-interactive filter/selection tool available.

    If the option -v is specified, the filtering is inverted.

-  INTERACTIVE FILTERING
-    You can also use the interactive mode, enabled with "-I" to filter and

-  PUT FIELDS TO CLIPBOARD
-    You can let tablizer put fields to the clipboard using the option "-y".
-    This best fits the use-case when the result of your filtering yields
-    just one row. For example:
-
-        cloudctl cluster ls | tablizer -yid matchbox
-
-    If "matchbox" matches one cluster, you can immediately use the id of
-    that cluster somewhere else and paste it. Of course, if there are
-    multiple matches, then all id's will be put into the clipboard separated
-    by one space.
-
  ENVIRONMENT VARIABLES
    tablizer supports certain environment variables which use can use to
    influence program behavior. Commandline flags have always precedence
    over environment variables.

-    <T_HEADER_NUMBERING> - enable numbering of header fields, like -n.
+    <T_NO_HEADER_NUMBERING> - disable numbering of header fields, like -n.
    <T_COLUMNS> - comma separated list of columns to output, like -c
    <NO_COLORS> - disable colorization of matches, like -N

-You can also use the interactive mode, enabled with C<-I> to filter

-To enter e filter, hit C</>, enter a filter string and finish with
-C<ENTER>. Use C<SPACE> to select/deselect rows, use C<a> to select all
-(visible) rows.

-Commit your selection with C<q>. The selected rows are being fed to
