What is the problem of manipulating cells by el-table components in elementUI?

the use of elementUI, in a project requires a single-row N-column table. The number of columns is not fixed and needs to be generated dynamically. And the contents of each cell provide editing function.

< hr >

dynamically generated columns are implemented by el-table-column

column editing is implemented by custom cell contents

the above two requirements can be implemented separately, but after merging, the data cannot be rendered
