[Enhancement] [table] el-table's filter icon looks like a sort icon

[Karolis-Stoncius]

Feature type: Enhancement

Details

• Enhanced component name: table

Description

Current icon for filtering table content is an arrow, which looks like it's for sorting. I'd suggest changing the icon to <el-icon><Filter /></el-icon> or something similar.
Making the filter icon customizable would be even better, but it's probably too much work for such a simple thing.

Additional comments

If it's not something the devs are wiling to pick up, I could try to fork the repo and implement it myself if necessary
