Take a look at http://www.wicketframework.org/wicket-extensions/apidocs/wicket/extensions/markup/html/tree/table/ColumnLocation.html
Specifying fixed size column should be no harder than adding them as LEFT or RIGHT columns instead of MIDDLE Column. MIDDLE column cannot have a fixed width. You should, however, be aware of a JavaScript i TreeTable that does resizing, see method init() in TreeTable: // Attach the javascript that resizes the header according to the body // This is necessary to support fixed position header. The header does // not // scroll together with body. The body contains vertical scrollbar. The // header width must be same as body content width, so that the columns // are properly aligned. Maybe you need to remove this, or at least modify the behavior... Or, you could always do as I did in my example - specify the width of the treetable greater than the size of the enclosing div (see earlier examples). >Hi, >I am new to the Wicket and am trying out the TreeTable example.
