title: SharePoint Column Formatting using JSON
body: <p>I'm trying to format a column from a list using JSON, I want to get rid of the "mailto:" from the field and add a little mail icon in front of the field value.</p>
  
  <p>I got the JSON adding the mail icon (at the end, after the field value - not bad for a first attempt), but no luck removing the "mailto:" from the field, any suggestions?</p>
  
  <pre><code>{
      "debugMode": true,
      "elmType": "div",
      "children": [
          {
              "elmType": "div",
              "style": {
                  "padding-right": "8px"
              },
              "txtContent": "@currentField"
          },
          {
              "elmType": "a",
              "attributes": {
                  "iconName": "Mail",
                  "class": "sp-field-quickActions",
                  "href": "@currentField"
              }
          }
      ]
  }
