Hello to edit the table
Go to your DNN installation files:
admin folder
Users
Edit the Profile.ascx file
In there you will see:
<dnn
rofileEditorControl id="ProfileProperties" runat="Server"
editcontrolstyle-cssclass="NormalTextBox"
enableClientValidation = "true"
errorstyle-cssclass="NormalRed"
groupHeaderStyle-cssclass="Head"
groupHeaderIncludeRule="True"
helpstyle-cssclass="Help"
labelstyle-cssclass="SubHead"
visibilitystyle-cssclass="Normal"
editcontrolwidth="525px"
labelwidth="50px"
width="675px"
groupByMode="Section" />
Here you can edit the label width to suit your needs,
thanks,
