The width attribute is optional for all columns. If the column width is not configured, the width of the individual columns is calculated automatically. By default, a width of 20% is assigned to the structure, and a width of 1% is assigned to each chart column. The remaining percentage is equally distributed to the other columns.
Since Excel and PDF reports do not contain chart columns, the layout is recalculated for a report, that is, the width of the chart columns is distributed to the columns visible in the report.
