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 Styling]]
|
||||
|
||||
## 🎯 한 줄 통찰 (One-line insight)
|
||||
Tables become readable and attractive by adding cell padding, horizontal dividers, hover highlighting, zebra striping, and header colors. [S1]
|
||||
|
||||
## 🧠 핵심 개념 (Core concepts)
|
||||
- **Padding adds breathing room** — to add more space between the inner borders and the content in a table, use the `padding` property on `<td>` and `<th>` elements. [S1]
|
||||
- **Horizontal dividers** — to create horizontal dividers for a table, add the `border-bottom` property to `<th>` and `<td>` elements. [S1]
|
||||
- **Hover highlighting** — use the CSS `:hover` selector on `<tr>` to highlight table rows on mouse over. [S1]
|
||||
- **Zebra striping** — for zebra-striped tables, use the `nth-child()` selector and add a `background-color` to all even (or odd) table rows. [S1]
|
||||
- **Header coloring** — specify a `background-color` and a text `color` for the `<th>` elements. [S1]
|
||||
|
||||
## 🧩 추출된 패턴 (Extracted patterns)
|
||||
- **Group selector for cells** — style `th, td` together to apply padding/borders uniformly across header and data cells. [S1]
|
||||
- **Row-level pseudo-classes** — `tr:hover` and `tr:nth-child(even)` target whole rows for interactivity and striping. [S1]
|
||||
|
||||
## 📖 세부 내용 (Details)
|
||||
**CSS Table Padding**
|
||||
To add some more space between the inner borders and the content in a table, use the `padding` property on `<td>` and `<th>` elements: [S1]
|
||||
```css
|
||||
th, td {
|
||||
padding: 10px;
|
||||
text-align: left;
|
||||
}
|
||||
```
|
||||
|
||||
**CSS Horizontal Dividers**
|
||||
To create horizontal dividers for a table, add the `border-bottom` property to `<th>` and `<td>` elements: [S1]
|
||||
```css
|
||||
th, td {
|
||||
border-bottom: 1px solid #ddd;
|
||||
}
|
||||
```
|
||||
|
||||
**CSS Hoverable Table**
|
||||
Use the CSS `:hover` selector on `<tr>` to highlight table rows on mouse over: [S1]
|
||||
```css
|
||||
tr:hover {background-color: coral;}
|
||||
```
|
||||
|
||||
**CSS Zebra-striped Table**
|
||||
For zebra-striped tables, use the `nth-child()` selector and add a `background-color` to all even (or odd) table rows: [S1]
|
||||
```css
|
||||
tr:nth-child(even) {background-color: #f2f2f2;}
|
||||
```
|
||||
|
||||
**CSS Table Color**
|
||||
The example below specifies a background color and a text color for the `<th>` elements: [S1]
|
||||
```css
|
||||
th {
|
||||
background-color: #04AA6D;
|
||||
color: white;
|
||||
}
|
||||
```
|
||||
|
||||
## 🛠️ 적용 사례 (Applied in summary)
|
||||
The page's own examples are the applied cases: 10px cell padding, 1px horizontal dividers, coral hover rows, `#f2f2f2` zebra striping on even rows, and a green (`#04AA6D`) header with white text. No external project/commit applications found in the source.

||||
|
||||
## 💻 코드 패턴 (Code patterns)
|
||||
Zebra striping (language: CSS):
|
||||

Hover highlight (language: CSS):
