Hiding Columns in Excel Workbooks using openxlsx

Question

I'm trying to hide columns in an Excel workbook I'm creating using the openxlsx package in R, but I'm not having any luck. I could make a pre-formatted Excel workbook and write data to it, but the number of columns that need to be hidden is variable. I've tried using:

 setColWidths(wb, sheet = "Sheet 1", cols = col_list, widths = 0)

where "col_list" is the list of columns that need to be hidden. When I open the saved workbook, the column widths are actually 0.38. If anybody has any ideas on how I might go about this, it would be much appreciated.

Answer 1

The documentation shows the fields for the formula as below:

setColWidths(wb, sheet, cols, widths = 8.43, hidden = rep(FALSE, length(cols)), ignoreMergedCells = FALSE)

So setting hidden = rep(TRUE, length(cols)) should hide your columns
