Suitelet Single Column Form

I'm trying to create a single column form using a suitelet. I'm not sure if this is just related to SS2.0 but it's putting a blank column to the right with everything I've tried. So I get my single column form but it only takes up half the page space.

Basically I have a select field followed by 2 inline HTML fields. Here is the code I've tried. Anyone else have issues with this or better yet, a solution?

Thanks!

             if(request.method == 'GET'){                  // create the form                  var form = serverWidget.createForm({                      title: "Funding Request"                  });                  form.addSubmitButton({                      label: "Create Invoice"                  });                  //form.clientScriptModulePath = 'SuiteScripts/SWK/somejavascriptfile.js'; (-- this not working yet)                  form.clientScriptFileId = '1077448';                                    /*************** Client information ***********************/                  var clientFldGrp = form.addFieldGroup({                      id : 'clientfldgroup',                      label : 'Client Information'                  });                  //clientFldGrp.isSingleColumn = true;                                    var clientFld = form.addField({                      id : 'custpage_client',                      type : serverWidget.FieldType.SELECT,                      label : 'Client',                      container: 'clientfldgroup'                  });                  //clientFld.breakType = serverWidget.FieldBreakType.STARTCOL; // STARTCOL STARTROW NONE                                    var searchDataTableFld = form.addField({                      id : 'custpage_search_datatable',                      type : serverWidget.FieldType.INLINEHTML,                      label : 'Search HTML',                      container: 'clientfldgroup'                  });                  //searchDataTableFld.breakType = serverWidget.FieldBreakType.STARTCOL;                                    var openPODataTableFld = form.addField({                      id :
