  <Select placeholder="MT" style={{ width: 55 }}>
    <Select.Option value="MT">MT</Select.Option>

我想为此添加一个默认值。你能帮忙吗

使用defaultValue属性，

<Select defaultValue="MT"/>

重量选项示例：

const weightOptions = ["MT", "KG"];

const addWeightOptions = weightOptions =>
  weightOptions.map((weight, i) => (
    <Select.Option key={`${weight}-${i}`} value={weight}>
      {weight}
    </Select.Option>
  ));

<Select
    placeholder="Select Weight Units"
    defaultValue={weightOptions[0]}
  >
    {addWeightOptions(weightOptions)}
</Select>
