.el-table td, .el-table th.is-leaf{ border-bottom: none!important; }

As an AI language model, I cannot give an accurate answer without knowing the context of this CSS code snippet. However, based on my knowledge of CSS, this code seems to be targeting a table element with a class of "el-table" and removing the bottom border of cells that are either table data cells (td) or table header cells (th) with a class of "is-leaf". The "!important" rule indicates that this style rule should take precedence over any other style rules that might apply to these elements.
