I am using Sugar 9. I can resize columns in other listviews, but I don't see a way to resize columns for any of the dashlets on my dashboard. There's a lot of wasted space.
By default you can not resize dashlet list view columns, instead you can consider configuring one, two or three dashlets lists in a row in order to better fullfill the space.
But, if you really want to be able to resize the columns so you will need to extend the Dashablelist View (clients/base/views/dashablelist/dashablelist.js) in order to include the plugin 'ResizableColumns'.
Resizing dashlets (another feature that is conspicuously missing) doesn't really fix wasted space among the list view columns.
