docs(10_Wiki): Dev 폴더 누락분 반영 — Topic_Programming으로 통합

이전 재구성 작업에서 Dev/ 폴더가 누락되었던 것을 반영.

- Dev/Topic_Programming(중첩 폴더, 78개)은 Dev 자체 최상위 폴더들
  (Architecture/Conventions/Engineering_Intelligence 등)과 완전 중복이라 제거.
- Dev 최상위 엔지니어링 지식 폴더(Architecture/Conventions/Engineering_Intelligence/
  Failure_Library/Generalized_Principles/Language/Pattern_Catalog/Platform_Guides/
  Subsystems, 77개)는 이미 Topic_Programming/Topic_Programming에 더 최신 버전이
  존재해 중복 제거(고유 콘텐츠 1개는 예외 처리하여 이동 보존).
- Dev의 W3Schools 언어 튜토리얼 폴더(Topic_C/CPP/CSS/CSharp/HOWTO/HTML/Java/
  JavaScript/PHP/Python/SQL/W3CSS, 1201개)는 전부 Topic_Programming 하위로 이동.
- 에이전트 운영 상태(.astra/docs)는 그대로 유지, 콘텐츠 폴더만 정리.
- Topic_Programming 최종 문서 수: 2784 → 3985.

+# [[CSS Table Responsive]]
+
+## 🎯 한 줄 통찰 (One-line insight)
+Wrap a table in a container with `overflow-x: auto;` so it shows a horizontal scrollbar instead of breaking the layout on small screens. [S1]
+
+## 🧠 핵심 개념 (Core concepts)
+- **Responsive table behavior** — a responsive table will display a horizontal scrollbar if the screen is too small to display the full content. [S1]
+- **Wrap in a container** — wrap the `<table>` element in a `<div>` container. [S1]
+- **Enable horizontal overflow** — set the `overflow-x` property to `auto` for the `<div>` element. [S1]
+
+## 🧩 추출된 패턴 (Extracted patterns)
+- **Container + overflow pattern** — `<div>` wrapper with `overflow-x: auto;` is the standard way to make a wide table scroll horizontally within its space. [S1]
+
+## 📖 세부 내용 (Details)
+A responsive table will display a horizontal scrollbar if the screen is too small to display the full content. [S1]
+
+To make the table responsive, wrap the `<table>` element in a `<div>` container, and set the `overflow-x` property to `auto` for the `<div>` element: [S1]
+```css
+div.tablecontainer {
+  overflow-x: auto;
+}
+```
+
+**Note:** In OS X Lion (on Mac), scrollbars are hidden by default and are only shown when being used (even though `overflow:scroll` is set). [S1]
+
+The page also references additional examples such as "Make a fancy table" and "Add and position a table caption." [S1]
+
+**CSS Table Properties (reference table)** [S1]
+
+| Property | Description |
+|----------|-------------|
+| border | Sets all the border properties in one declaration |
+| border-collapse | Specifies whether or not table borders should be collapsed |
+| border-spacing | Specifies the distance between the borders of adjacent cells |
+| caption-side | Specifies the placement of a table caption |
+| empty-cells | Specifies whether or not to display borders and background on empty cells |
+| table-layout | Sets the layout algorithm to be used for a table |
+
