How to change the width of columns
Column widths will initially be set to those in the formatting template. The formatting template is initially set to the “Gridlines template.xlsx” file in your OBXComponents folder in your Documents folder.
To change column widths, open that template file in Excel and adjust the column widths as desired. Then save it. You can save it under a different name but you will then need to tell Openbox to use this new template file. See Changing how inputs and calculations are laid out for how to do this.
Note that you can also tell Openbox to autofit columns to their contents. This is an option in the main Openbox settings window. Again, see Changing how inputs and calculations are laid out for more detail.
