Here is something I quickly wrote up:
First, define some labels for the columns of the ToC —
\definesynonyms[toclabel][toclabel][\TOCLabel]
\setupsynonyms[toclabel][textstyle=\sc]
\toclabel{TOCNumberLabel}{Chapter}
\toclabel{TOCTitleLabel}{Title}
\toclabel{TOCPageLabel}{Page}
Then compute the width of the chapter-number and page-number labels
\setwidthof\TOCLabel{TOCNumberLabel}\to\TOCNumberLabelWidth
\setwidthof\TOCLabel{TOCPageLabel}\to\TOCPageLabelWidth
and define a 'paragraphs' block with 3 columns with a separation of 1em between
each column
\defineparagraphs
[TOCpar]
[n=3]
\setupparagraphs
[TOCpar]
[each]
[distance=1em]
Set the width of the first column to the width of the label (and center chapter
number)
\setupparagraphs
[TOCpar]
[1]
[width=\dimexpr\TOCNumberLabelWidth,
align=middle]
and similarly for the third column (and center the page number)
\setupparagraphs
[TOCpar]
[3]
[width=\dimexpr\TOCPageLabelWidth,
align=middle]
Finally, wrap it all up in the macro
\define[3]\TOCEntry{%
\startTOC
#1 \TOCpar #2 \TOCpar #3%
\stopTOC%
}
and indicate the command to use in the setup
\setuplist
[chapter]
[alternative=interactive,
command=\TOCEntry,
after=\endgraf] % required
The ToC along with column labels is placed with
\TOCLabel{TOCNumberLabel}%
\hfill\TOCLabel{TOCTitleLabel}\hfill%
\TOCLabel{TOCPageLabel}
\placecontent
Of course, you can choose to not set the 'align' keys in \setupparagraphs[TOC]
if center alignment is not required/desired.
Hope this helps.
Best,
kauśika
