ErrColumnWidth

ErrColumnWidth

Error message

the width of the column must be less than or equal to %d characters

What it means

Sentinel error ErrColumnWidth returned by SetColWidth when the requested column width exceeds MaxColumnWidth. It fires as a generic validation guard in SetColWidth: the width argument at fault is any value greater than the maximum allowed column width, and the operation is aborted before the column definition is modified.
