Q&A

Why all columns are resized while I'm resizing

Ant Design makes the column width reactive. If all columns that given an init width via width can't fill the table, Ant Design will let column calculate a suitable width for itself. So you should make sure the sum of all columns width is greater than the table width. Anothor feasible way is to define a auto width column at the end (such as the example case).

Why vue 3

Ant Design 2.x supports vue 3.

Must the columns be defined as a ref variable

Sure. The width of column will be change, so it must be a reactive variable.
