增加样式：

.el-table .cell {
    white-space: pre-line;
}

<el-table-column align="left" width="400px"
                prop="title"
                label="标题"
                :formatter="wrapText"
                >
        </el-table-column>

wrapText: function(row, column, cellValue){
    return cellValue.replace(",","\n");
},
