Version

4.2.1

Environment

"vue": "^3.2.36"

Reproduction link

Steps to reproduce

1. Create a table component
2. Set the width of a column item to 0 and the width of other columns to greater than 0
3. Set table v-show to false and scroll to y
4. Change the v-show to true

What is expected?

The contents of the table are displayed normally, such as the table header

What is actually happening?

The header is still not displayed

I have tried to locate it and found that in the component MeasureCell, the onResize of VCResizeObserver does not trigger the columnResize event for a column of width equal to 0 when the v-show of the table changes to true. The result is that useColumnWidth will still be undefined and the visibility of the table inside the table header will still be hidden. Hopefully this will help you
