Hello, The code below works fine, but I am not sure if it is correct way. Is there another way to change the width of a GLMTableColumn? | finder d | finder := GLMFinder new. d := finder table display: [ :x | x lines ]. d addColumn: (GLMTableColumn new title: 'v.'; computation: [ :e | '999']; width: 30). d addColumn: (GLMTableColumn new title: 'aut.'; computation: [ :e | 'anAuthor']; width: 70). d addColumn: (GLMTableColumn new title: 'code'; computation: #asString ). finder openOn: (Date>>#addMonths:) getSource thanks! -- Andre Hora
