@Discovery_TR. Sorry for responding to your question after such a long time. The way that I setup controlling the width is to specify the “Ratio of Name Column Width to Other Columns” in the plugins manager. The default value is 2, which means that the Name column will be twice as wide as the date or size column. The date and size columns will have the same width.
From looking at your picture, what is happening is that the file names are overflowing the next line.
Hope this helps.
