I'm trying to add images to all cells in a particular column of the
tablelist widget. However, I'm not grokking how to do this.

This is my example code:

foreach row 0 {
    $tbl cellconfigure 0,$row -image folder
}


'Walk' through your code:

foreach row 0 {
# You are saying for each value in the list, and your list only one
value,
# and that value is 0, assign that value to the variable row.
    $tbl cellconfigure 0,$row -image folder
# Cellconfigure the table at column 0 and at specified row to the image
of a folder.
# Remember now that your list only has a single value and that is zero
so only
# cell 0,0 will be configured.
}
# End of foreach. Since your list only has a single value the foreach
will only
# iterate once (for the value 0). The foreach loop now terminates.

What you should have done is:
set rows [list 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15]
foreach row $rows {
  ...

What you probably should be doing is:
for {set row 0} {$row < $max_row} {incr row} {
  ...


The idea is that this snippet will iterate through each cell of column 0
and append the image. But it adds only one folder, to the top cell.


That's not recursive now is it? It's iterative.

That helped, thanks.
