# [[CSS Table Size]]

## 🎯 한 줄 통찰 (One-line insight)
The `width` and `height` properties control the size of a table and its cells, accepting percentage, fixed-pixel, or `auto` values. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`width` sets table width** — the CSS `width` property is used to set the width of a table. [S1]
- **Three width units** — width can be set in percent (%), as a fixed length (px), or by the `auto` keyword. [S1]
- **`height` sets table height** — the CSS `height` property is used to set the height of a table; it can likewise be set in percent (%), as a fixed length (px), or by `auto`. [S1]
- **Auto = browser calculates** — using `width: auto;` lets the browser calculate the width. [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Full-width pattern** — `width: 100%;` makes a table span the entire screen. [S1]
- **Fractional-width pattern** — `width: 50%;` makes a table span half the page. [S1]
- **Cell sizing** — apply `height` to `th` (or `td`) to size individual cells, e.g. set header height. [S1]

## 📖 세부 내용 (Details)
**CSS Table Width**
The CSS `width` property is used to set the width of a table. The width can be set: in percent (%), as a fixed length (px), or by the `auto` keyword. [S1]

To create a table that spans the entire screen (full-width), use `width: 100%;`: [S1]
```css
table {
  width: 100%;
}
```

To create a table that spans half the page, use `width: 50%;`: [S1]
```css
table {
  width: 50%;
}
```

To create a table with a fixed width, use `width: 500px`: [S1]
```css
table {
  width: 500px;
}
```

To let the browser calculate the width, use `width: auto;`: [S1]
```css
table {
  width: auto;
}
```

**CSS Table Height**
The CSS `height` property is used to set the height of a table. The height can be set: in percent (%), as a fixed length (px), or by the `auto` keyword. The example below sets the height of the table headers (`<th>`) to 70px: [S1]
```css
th {
  height: 70px;
}
```

## 🛠️ 적용 사례 (Applied in summary)
The page's own examples are the applied cases: full-width (`100%`), half-width (`50%`), fixed (`500px`), and `auto` table widths, plus a 70px header height. No external project/commit applications found in the source.

## 💻 코드 패턴 (Code patterns)
Set table width (language: CSS):
```css
table {
  width: 100%;
}
```
Set cell height (language: CSS):
```css
th {
  height: 70px;
}
```
