Ok now the example works. Now on to my next nuance. The detail grid consists of columns in 3 groups (hence three super headings using this example). However the first and 3rd group can have columns either not visible or in a different order via the visibleindex property.
How do I calculate the the width for these 3 sections so that this CustomColumnMnagerRow can display headers for the 3 sections? Each of the sections has an absolute contiguous ranges of column number (original define order). So basically I hand the first super header to cover columns in the range 0-9, 2nd 10-15, 3rd 16 – 25. As mentioned above, some of the columns in the first and 3rd section may either not be visible or in a different order within the section (never across sections).
