Dear Jeong Dal, I use the following functions to control the start and end of columns in a columnset: 
\setuplayout[grid=yes] \emptylines[...] % see the command \emptylines in ConTeXtgarden \setupcolumnsetstart[...][...][...][...] % see the manual COLUMNS, page 9 \setupcolumnsetlines[...][...][...][...] % see the manual COLUMNS, page 9 %\showgrid % uncomment if you want to see the grid lines and line numbers You find the manual COLUMNS under the heading 'Layout' on https://wiki.contextgarden.net/Manuals. With kind regards, Sytse

Dear all,

I use the following code to make test. To make the same height blank spaces after the problems, I use \vfill before \column. The problem is that the second \column creates extra blank page. But, without the second \column, the height of blank spaces of the second column are different.

Is there a way to make the blank spaces height same while not to create a blank page?

Thank you for reading.

Best regards,

Dalyoung
