header.getResizeHandler() sets column size to null after it is resized to 0

React v18.3.1

Describe the bug and the steps to reproduce it

When a column’s minSize is set to 0 and the column is resized all the way down to 0px width, it becomes impossible to resize it again. The column appears to get stuck at width 0.

From debugging, this seems to happen because the resize handler sets the column size to null when the size reaches 0.

Steps to Reproduce

1. Open the provided CodeSandbox (fork of the official Column Resizing Performant example here, only difference is that defaultColumn.minSize is set to 0 in useReactTable)
2. Resize any column down to width of 0px.
3. Try to resize the same column back to a width greater than 0.

Expected Behavior


The column should be resizable again after reaching width 0.

Actual Behavior

Once the column width reaches 0, it cannot be resized anymore.
