+# 화면 설정 모달 개선 완료 보고서
+
+## 개요
+화면 관리에서 화면 노드 우클릭 시 열리는 설정 모달을 대폭 개선하여, 테이블 정보 시각화, 필드 매핑 확인, 컬럼 변경/추가/제거 기능, 조인 설정 기능, 실시간 프리뷰 기능을 강화했습니다.
+
+## 주요 개선 사항
+
+### 1. 화면 개요 탭 통합 개선
+
+#### 1.1 필드 매핑 탭 → 개요 탭 통합
+- 기존 "필드 매핑" 탭 제거
+- 필드 매핑 정보를 개요 탭의 메인/필터 테이블 아코디언에 통합 표시
+- 더 직관적이고 간결한 UI 제공
+
+#### 1.2 메인 테이블 아코디언
+- 메인 테이블(예: `customer_mng`)을 아코디언 형식으로 표시
+- 클릭 시 테이블의 모든 컬럼 정보 표시
+- **1열 레이아웃**: 컬럼 정보를 세로로 배치
+- 화면에서 사용 중인 컬럼은 **파란색 배경 + "필드" 배지**로 강조
+- **컬럼 정렬**: 
+  - 사용중인 필드가 상단에 표시
+  - 화면에 표시되는 순서대로 정렬 (y좌표 기준)
+  - 미사용 컬럼은 하단에 표시
+
+#### 1.3 필터 테이블 아코디언
+- 필터 테이블(예: `customer_item_mapping`)을 아코디언 형식으로 표시
+- 클릭 시 테이블의 모든 컬럼 정보 표시
+- 컬럼별 색상 구분:
+  - **파란색**: 화면에서 사용 중인 컬럼 (필드)
+  - **보라색**: 필터 키 컬럼 (WHERE 절에 사용)
+  - **주황색**: 조인 키 컬럼 (JOIN 조건에 사용)
+- **다중 배지 표시**: 컬럼이 필드이면서 조인/필터 키인 경우 배지 동시 표시
+- 필터 연결 정보 표시 (예: `→ customer_mng`)
+
+#### 1.4 컬럼 레이아웃 순서
+- **순서**: `컬럼명 | 배지 | 데이터타입`
+- 예: `거래처 코드` `[필드]` `character varying`
+- 데이터타입은 오른쪽 정렬
+
+#### 1.5 클릭 스타일 개선
+- **테두리 제거**: ring-2, ring-offset 등 제거
+- **강조 색상 연하게**: 
+  - 선택됨: `bg-blue-100 border-blue-300`
+  - 미선택: `bg-blue-50 border-blue-200`
+- 더 부드러운 시각적 피드백
+
+#### 1.6 패널 높이 동기화
+- 왼쪽(컬럼 목록)과 오른쪽(설정 패널) 동일한 `max-h-[350px]` 적용
+- `overflow-y-auto`로 스크롤 처리
+- `items-stretch`로 양쪽 패널 높이 동기화
+
+### 2. 컬럼 변경 기능
+
+#### 2.1 인라인 컬럼 편집
+- 사용중인 필드(파란색 배경)를 클릭하면 우측에 "컬럼 설정" 패널 표시
+- 패널 정보:
+  - **화면 필드**: 컬럼 한글명 표시 (예: "거래처 코드")
+  - **현재 컬럼**: 영문 컬럼명 표시 (예: `customer_code`)
+  - **컬럼 변경**: 드롭다운으로 다른 컬럼 선택
+- 검색 기능으로 컬럼 빠르게 찾기
+
+#### 2.2 실시간 반영
+- 컬럼 변경 후 **페이지 새로고침 없이** 실시간 반영
+- `onRefresh` 콜백으로 데이터 리로드 + iframe 새로고침
+- 더 빠른 사용자 경험
+
+#### 2.3 변경사항 저장
+- `screenApi.saveLayout()` 사용하여 **화면 디자이너와 동일한 테이블에 저장**
+- 저장 위치:
+  - `componentConfig.leftPanel.columns` (분할 패널)
+  - `componentConfig.rightPanel.columns` (분할 패널)
+  - `usedColumns` 배열
+  - `bindField` 필드
+  - `fieldMapping` 배열
+
+### 3. 필드 추가/제거 기능 (신규)
+
+#### 3.1 필드 추가
+- 비필드 컬럼(회색/흰색 배경) 클릭
+- "컬럼 설정" 패널에 컬럼 정보 표시
+- **"필드로 추가"** 버튼 클릭 → 해당 컬럼이 화면 필드로 추가됨
+- 버튼 스타일: `text-blue-600 border-blue-300 hover:bg-blue-50` (파란색 테두리)
+
+#### 3.2 필드 제거
+- 기존 필드(파란색 배경) 클릭
+- "컬럼 설정" 패널에 필드 정보 표시
+- **"필드에서 제거"** 버튼 클릭 → 해당 필드가 화면에서 제거됨
+- 버튼 스타일: `text-red-600 border-red-300 hover:bg-red-50` (빨간색 테두리)
+
+#### 3.3 저장 로직
+```typescript
+// 필드 추가: 배열에 새 컬럼 추가
+if (isAddingField) {
+  return {
+    ...comp,
+    componentConfig: {
+      ...comp.componentConfig,
+      leftPanel: {
+        ...comp.componentConfig.leftPanel,
+        columns: [...leftColumns, { name: newColumn, columnName: newColumn }],
+      },
+    },
+  };
+}
+
+// 필드 제거: 배열에서 해당 컬럼 제거
+if (isRemovingField) {
+  const filteredColumns = leftColumns.filter((_, i) => i !== columnIdx);
+  return {
+    ...comp,
+    componentConfig: {
+      ...comp.componentConfig,
+      leftPanel: {
+        ...comp.componentConfig.leftPanel,
+        columns: filteredColumns,
+      },
+    },
+  };
+}
+```
+
+#### 3.4 적용 범위
+- 메인 테이블 아코디언: 필드 추가/제거 가능
+- 필터 테이블 아코디언: 필드 추가/제거 가능
+- `usedColumns`, `componentConfig.usedColumns`, `componentConfig.columns`, `leftPanel.columns`, `rightPanel.columns` 모두 지원
+
+### 4. 화면 프리뷰 상시 표시
+
+#### 4.1 레이아웃 변경
+- 기존: 탭으로 프리뷰 전환
+- 개선: **모달 우측에 프리뷰 상시 표시**
+- 모달 크기 확대 (1600px 최대 너비)
+- 좌측 40% (탭 콘텐츠) / 우측 60% (프리뷰)
+
+#### 4.2 줌/드래그/클릭 기능 (react-zoom-pan-pinch 라이브러리)
+- **휠 스크롤**: 마우스 포인터 위치 기준 확대/축소 (20% ~ 300%)
+- **드래그**: 마우스 왼쪽 버튼으로 화면 이동 (5px 이상 이동 시)
+- **클릭**: iframe 내부 요소 정상 클릭 가능
+  - 버튼, 셀렉트박스, 체크박스, 테이블 행 클릭
+  - 인풋박스/텍스트박스 포커스 및 입력
+  - X버튼(닫기) 등 SVG 아이콘 버튼 클릭
+
+#### 4.3 클릭 좌표 보정 시스템
+- 줌 상태에서도 정확한 클릭 위치 계산
+- `designWidth / rect.width` 비율로 좌표 변환
+- 오버레이 방식으로 드래그와 클릭 분리 처리
+
+### 5. 필드+조인 컬럼 스타일 개선
+
+#### 5.1 다중 역할 컬럼 표시
+- 컬럼이 **필드이면서 조인 키**인 경우:
+  - **파란색 배경** (필드 기준)
+  - **왼쪽에 주황색 세로 선** (`border-l-4 border-l-orange-500`)
+  - 배지: `조인` `필드` 동시 표시
+- 컬럼이 **필드이면서 필터 키**인 경우:
+  - **파란색 배경** (필드 기준)
+  - **왼쪽에 보라색 세로 선** (`border-l-4 border-l-purple-400`)
+  - 배지: `필터` `필드` 동시 표시
+
+#### 5.2 조인 컬럼도 필드로 인식
+- `filterTableColumnMappings` 생성 시 조인 컬럼(`ft.joinColumnRefs`)도 포함
+- 조인 테이블 데이터를 화면에서 보여주므로 필드로 간주
+
+#### 5.3 컬럼 설정 패널 - 조인 정보 표시
+- 조인 키 클릭 시 패널에 조인 정보 표시:
+  - **대상 테이블**: item_info (실제 참조 테이블)
+  - **연결 컬럼**: item_number (참조 컬럼)
+
+### 6. 조인 관계 설정/수정 기능
+
+#### 6.1 기능 설명
+- 컬럼 설정 패널에서 **조인 관계 직접 수정** 가능
+- **모든 컬럼에서 조인 설정 가능** (기존 조인 키가 아닌 컬럼도 포함)
+- 테이블 타입 관리(`column_labels` 테이블)와 동일한 저장 위치 사용
+
+#### 6.2 저장 테이블
+```
+column_labels 테이블:
+├── reference_table   (참조 테이블명)
+├── reference_column  (참조 컬럼 - 보통 PK)
+└── display_column    (화면에 표시할 컬럼)
+```
+
+#### 6.3 구현된 UI
+1. **컬럼 클릭** → 컬럼 설정 패널 표시
+2. **"조인" 섹션 확인**:
+   - 조인 설정 있음: "편집" 버튼
+   - 조인 설정 없음: "추가" 버튼
+3. **드롭다운으로 설정** (모두 검색 가능):
+   - 대상 테이블: 전체 테이블 목록에서 검색/선택
+   - 연결 컬럼 (PK): 선택한 테이블의 컬럼 중 검색/선택
+   - 표시 컬럼: 화면에 표시할 컬럼 검색/선택
+4. **저장 버튼** → `column_labels` 테이블에 저장
+5. **취소 버튼** → 편집 취소
+
+#### 6.4 검색 가능한 드롭다운
+- Popover + Command 컴포넌트 사용
+- 실시간 텍스트 검색 지원
+- 대상 테이블, 연결 컬럼, 표시 컬럼 모두 검색 가능
+
+#### 6.5 API 연동
+- **테이블 목록 조회**: `tableManagementApi.getTableList()`
+- **컬럼 목록 조회**: `tableManagementApi.getColumnList(tableName)`
+- **저장**: `tableManagementApi.updateColumnSettings(tableName, columnName, settings)`
+
+#### 6.6 메인 테이블에도 조인 설정 적용
+- 메인 테이블 아코디언에서도 조인 설정 가능
+- 필터 테이블과 동일한 UI/기능 제공
+
+#### 6.7 조인 데이터 소스 수정
+- 기존 조인 키 클릭 시 `joinRef.refTable` 값을 사용
+- 예: `품목 ID` → `item_info` (실제 참조 테이블)
+- `mainTable` 대신 `joinRef.refTable` 사용으로 정확한 테이블 표시
+
+### 7. 배지 순서 및 스타일
+- **배지 순서**: `필터` → `조인` → `필드` (필드가 맨 뒤)
+- **조인 배지**: 주황색 배경 (`bg-orange-200 text-orange-700`)
+- **필터 배지**: 보라색 배경 (`bg-purple-200 text-purple-700`)
+- **필드 배지**: 파란색 배경 (`bg-blue-500 text-white`)
+
+### 8. 컴포넌트 통합 리팩토링
+
+#### 8.1 `TableColumnAccordion` 통합 컴포넌트
+- 기존 `MainTableAccordion`과 `FilterTableAccordion`을 하나의 컴포넌트로 통합
+- `tableType` prop으로 "main" 또는 "filter" 구분
+- 코드 중복 제거 및 유지보수성 향상
+
+#### 8.2 Props 구조
+```typescript
+interface TableColumnAccordionProps {
+  tableName: string;
+  tableLabel?: string;
+  tableType: "main" | "filter";
+  columnMappings?: ColumnMapping[];
+  onColumnChange?: (fieldLabel: string, oldColumn: string, newColumn: string) => void;
+  onColumnReorder?: (newOrder: string[]) => void;
+  onJoinSettingSaved?: () => void;
+  // 필터 테이블 전용 props
+  mainTable?: string;
+  filterKeyMapping?: FilterKeyMapping;
+  joinColumnRefs?: JoinColumnRef[];
+}
+```
+
+#### 8.3 동적 테마 적용
+- 메인 테이블: 파란색 테마 (`blue`)
+- 필터 테이블: 보라색 테마 (`purple`)
+- `themeColor`, `themeIcon`, `themeBadge` 변수로 동적 스타일 적용
+
+### 9. 드래그 앤 드롭 컬럼 순서 변경
+
+#### 9.1 기능 설명
+- 사용 중인 컬럼(필드)을 드래그하여 순서 변경 가능
+- 드래그 중에는 시각적으로만 순서 변경, **드롭 시에만 저장**
+- 드래그 취소(영역 밖으로 나간 경우) 시 원래 순서로 복원
+
+#### 9.2 드래그 상태 관리
+```typescript
+// 드래그 상태
+const [draggedIndex, setDraggedIndex] = useState<number | null>(null);
+const [localColumnOrder, setLocalColumnOrder] = useState<string[] | null>(null);
+```
+
+#### 9.3 드래그 핸들러
+```typescript
+// 드래그 시작: 현재 순서를 로컬 상태로 저장
+const handleDragStart = (e: React.DragEvent, index: number) => {
+  setDraggedIndex(index);
+  const usedColumns = sortedColumns.filter(col => columnMappingMap.has(col.columnName.toLowerCase()));
+  setLocalColumnOrder(usedColumns.map(col => col.columnName));
+};
+
+// 드래그 중: 로컬 순서만 변경 (저장하지 않음)
+const handleDragOver = (e: React.DragEvent, hoverIndex: number) => {
+  if (draggedIndex === null || draggedIndex === hoverIndex || !localColumnOrder) return;
+  const newOrder = [...localColumnOrder];
+  const draggedItem = newOrder[draggedIndex];
+  newOrder.splice(draggedIndex, 1);
+  newOrder.splice(hoverIndex, 0, draggedItem);
+  setDraggedIndex(hoverIndex);
+  setLocalColumnOrder(newOrder);
+};
+
+// 드롭: 최종 순서로 저장
+const handleDrop = (e: React.DragEvent) => {
+  if (localColumnOrder && onColumnReorder) {
+    onColumnReorder(localColumnOrder);
+  }
+  setDraggedIndex(null);
+  setLocalColumnOrder(null);
+};
+
+// 드래그 취소
+const handleDragEnd = () => {
+  setDraggedIndex(null);
+  setLocalColumnOrder(null);
+};
+```
+
+#### 9.4 시각적 피드백
+- 드래그 가능한 컬럼: `cursor-grab active:cursor-grabbing`
+- 드래그 중인 컬럼: `opacity-50 scale-95`
+- 드래그 중 실시간 순서 변경 표시
+
+#### 9.5 저장 로직 (`handleColumnReorder`)
+```typescript
+const handleColumnReorder = async (tableType: "main" | "filter", newOrder: string[]) => {
+  const currentLayout = await screenApi.getLayout(screenId);
+  
+  const updatedComponents = currentLayout.components.map((comp: any) => {
+    // leftPanel.columns 순서 변경
+    if (comp.componentConfig?.leftPanel?.columns) {
+      const leftColumns = comp.componentConfig.leftPanel.columns;
+      const reorderedColumns = newOrder.map(colName => 
+        leftColumns.find((col: any) => col.name?.toLowerCase() === colName.toLowerCase())
+      ).filter(Boolean);
+      const remainingColumns = leftColumns.filter((col: any) => 
+        !newOrder.some(n => n.toLowerCase() === col.name?.toLowerCase())
+      );
+      
+      return {
+        ...comp,
+        componentConfig: {
+          ...comp.componentConfig,
+          leftPanel: {
+            ...comp.componentConfig.leftPanel,
+            columns: [...reorderedColumns, ...remainingColumns],
+          },
+        },
+      };
+    }
+    return comp;
+  });
+
+  await screenApi.saveLayout(screenId, { ...currentLayout, components: updatedComponents });
+  onRefresh?.();
+};
+```
+
+#### 9.6 지원 범위
+- 메인 테이블: `onColumnReorder={(newOrder) => handleColumnReorder("main", newOrder)}`
+- 필터 테이블: `onColumnReorder={(newOrder) => handleColumnReorder("filter", newOrder)}`
+- 지원 배열:
+  - `componentConfig.leftPanel.columns`
+  - `componentConfig.rightPanel.columns`
+  - `componentConfig.usedColumns`
+  - `componentConfig.columns`
+
+## 기술 스택
+
+### 신규 의존성
+```bash
+npm install react-zoom-pan-pinch
+```
+
+### 사용된 컴포넌트
+- `TransformWrapper`, `TransformComponent` - 줌/드래그 기능
+- `Accordion`, `AccordionContent`, `AccordionItem`, `AccordionTrigger` - 아코디언 UI
+- `Popover`, `PopoverTrigger`, `PopoverContent` - 드롭다운 컨테이너
+- `Command`, `CommandInput`, `CommandList`, `CommandItem`, `CommandEmpty` - 검색 가능한 선택 UI
+- `tableManagementApi.getColumnList()` - 테이블 컬럼 정보 조회
+- `tableManagementApi.getTableList()` - 테이블 목록 조회
+- `tableManagementApi.updateColumnSettings()` - 조인 설정 저장
+- `screenApi.saveLayout()` - 레이아웃 저장
+- `screenApi.getLayout()` - 레이아웃 조회
