vxe-table 表格中实现多行文本的编辑

Vxe UI vue vxe-table 表格中实现多行文本的编辑

vxe-table v4.8+ 要在表格中使用多行文本编辑，可以通过设置行高方式，再设置 cell-config.verticalAlign: ‘top’ 单元格垂直对齐方式，实现顶部对齐，因为默认是居中对齐。

然后再微调一下样式，将文本域高度和宽度都是设置 100%，铺满单元格。再通过插槽自定义查看模式，同样微调高度和宽度铺满单元格。这样就能实表格单元格现多行的文本编辑。建议还是单行好一些，多行的效果不是很理想，适用于特殊需求。

      :cell-config="{verticalAlign: 'top'}"
      :row-config="{height: 100}"
      :edit-config="editConfig"
      :data="tableData">
