Editing Aligning columns from different markups

One can use <code>\markup \fill-line { \column { &quot;line1&quot; &quot;line2&quot; ... } \column { &quot;line1&quot; &quot;line2&quot; ... } }</code> to create text markup in multiple columns (for example, writing out the text of various stanzas after the score). However, the column widths are calculated from the contents, so columns from different markups are not aligned with each other.<br />
However, one can write a <code>\columns</code> macro, which makes each column exactly 1/n of the line-width, thus aligning even columns of different markups. The syntax stays the same, only that one has to use <code>\columns</code> instead of <code>\fill-line</code>:

<pre>\markup \columns {
  \column{&quot;default column 1&quot; &quot;line 2&quot;}
  \column{&quot;column 2, wider than the rest&quot; &quot;line 2&quot;}
  \column{&quot;c 3&quot; &quot;line 2&quot;}
}</pre>

\markup \justify {
  The default "\fill-line" uses columns, where the width is
  calculated from the contents. This means that two markups
  don't align their columns:
}

\markup \fill-line {
  \column { "default column 1" "line 2" }
  \column { "column 2, wider than the rest" "line 2" }
  \column { "c 3" "line 2" }
}
\markup \fill-line {
  \column { "col 1" "line 2" }
  \column{ "col 2" "line 2" }
  \column{ "Here, column 3 is wider." "line 2" }
}

\markup \fill-line {
  \column { "short" "line 2" }
  \column { "Long text, long text" "line 2" }
  \column { "another very long column text" "line 2" }
}

\markup \justify {
  However, one can write a "\columns" macro, which makes each column
  exactly 1/n of the line-width, thus aligning even columns of different
  markups:
}

\markup \columns {
  \column { "default column 1" "line 2" }
  \column { "column 2, wider than the rest" "line 2" }
  \column { "c 3" "line 2" }
}
\markup \columns {
  \column { "col 1" "line 2" }
  \column { "col 2" "line 2" }
  \column { "Here, column 3 is wider" "line 2" }
}
\markup \columns {
  \column { "short" "line 2"}
  \column { "Long text, long text" "line 2" }
  \column {"another very long column text" "line 2" }
}
