You could adjust the column width manually. In your table visualization, hover your mouse over your column heading that you want to "hide" and move it to the right until the mouse cursor changes to a <-||->, then you could adjust the width of this column.
For the better visualization, you 'd better turn off the Word wrap in the format pane. The below should be your expected output.
Hope it can help you!
