Do I need to type in a number to control the width of the columns in the Quick Report Spec Window?

No. Typing a number in this box controls the width, in pixels, of the specified column. If a width is not specified, Sesame will automatically size the column based on the data it contains and the available page width. If your columns are too close together, however, you can use this feature to increase the space between them.

Specified widths in a Print Only Report may not allow all of the columns to fit on the paper size specified. If only some of the columns have been assigned widths, those that have not will attempt to adapt their widths to cause the Report width to fit the width of the entire page. If the Print Only Report columns are too widespread across a page you can use these column widths to modify them.
