It is needed to be able to resize a column for all occurrences in a matrix. That is, not by dragging the size for each and every column value, but with setting a specific pt length in the visualizat...
It'd be useful if you could amend the column width property of a Matrix visual (ideally per field) via the format pane rather than manually dragging on the visual.
