Editor / Table mode / Fix field using directive (geonetwork#8261)

* Editor / Table mode / Fix field using directive

eg. when using thesaurus for a field in a table, the field was not displayed.

```xml
<tableFields>
    <table fieldset="false" for="mac:MI_Instrument">
      <header>
        <col label="mac:MI_Instrument"/>
        <col label="mac:MI_Platform"/>
        <col/>
      </header>
      <row>
        <col xpath="mac:identifier/*/mcc:code"
             use="data-gn-keyword-picker">
          <directiveAttributes data-thesaurus-key="local.theme.cersat_sensor"/>
        </col>
        <col xpath="mac:mountedOn/*/mac:identifier/*/mcc:code"
             use="data-gn-keyword-picker">
          <directiveAttributes data-thesaurus-key="local.theme.cersat_platform"/>
        </col>
        <col del=".."/>
      </row>
    </table>
```
