title: Change number format of input field in Antd's table-row-edit mode?
body: <p>I am using the <a href="https://2x.ant.design/components/table/" rel="nofollow noreferrer">Table Component of Ant Design v2.x</a> and I cannot upgrade. I would like to change the formatting of numbers in row-edit mode, since currently it is inconsistent: In Display mode I have German formatting (as desired), but once I click <code>edit</code>, numbers are formatted with American decimal separators:</p>
  
  <p><a href="https://i.stack.imgur.com/BMbsP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/BMbsP.png" alt="Screenshot of the issue"></a></p>
  
  <p>I understand that the table-component encapsulates an <a href="https://2x.ant.design/ccomponents/input-number/" rel="nofollow noreferrer">Input-Number component</a> which has the parameter <code>decimalSeparator</code> which I have to adjust. <strong>It is not at all obvious to me how I can pass-through that parameter from my parent (table) component column property to the underlying input-number component.</strong> </p>
  
  <p>As minimal code base to demonstrate that, let us consider the Typescript example code from <a href="https://ant.design/components/table/#components-table-demo-edit-row" rel="nofollow noreferrer">https://ant.design/components/table/#components-table-demo-edit-row</a> and focus on the column <code>age</code>. Assume that it is not an <code>age</code>, but rather a <strong>Value</strong> (e.g. of a trade).
  The (correct) formatting in the 2nd row of my screenshot I obtain with a <code>render</code>-function like this:</p>
  
  <pre class="lang-js prettyprint-override"><code>x.toLocaleString("de-DE", { style: 'currency', currency: ccy, currencyDisplay: "code", maximumFractionDigits: 2 });
  </code></pre>
  
  <p>where <code>x</code> is the value to be formatted and <code>ccy</code> is the currency-string to be displayed, in the screenshot it was just empty.</p>
  
  <p>What I <em>am</em> able to do is to specify whether a column is a <code>number</code>, a <code>string</code>, or something else. In the example source code, the corresponding part is:</p>
  
  <pre class="lang-js prettyprint-override"><code>interface Item {
    key: string;
    name: string;
    age: number;
    address: string;
  }
  </code></pre>
  
  <p>Looking forward to your help!</p>
