[Feature Request] need "Table Column" provide "overflow" without "show-tootip"

### Existing Component
是

### Component Name
el-table

### Description
I know that there is an attribute in the `el-table-column` tag of `el-table` which is `show-tooltip-when-overflow`. Sometimes it is convenient, but sometimes I just want the content to be automatically truncated without Show preview.

I know that I can customize the display of the columns and use custom css for my purposes, but I prefer a simple tag instead of `so many content with somany css`

Will you consider this suggestion?

Start at the el-table-column implementation and trace the existing show-tooltip-when-overflow behavior. Define how a column should truncate overflowing content without showing a preview tooltip, then verify the behavior against the el-table component; the issue does not name specific files or tests.
