 Column width can be adjusted by configuring `resizable`, enabling drag and drop, and column width can be limited by configuring `maxWidth` and `minWidth`.
+
+If you find that setting `scroll.width` does not allow horizontal scrollbar to appear, and dragging one column causes the other columns to become too narrow, set a `minWidth` for the column that is not set `width`.
