# [[CSS Table Alignment]]

## 🎯 한 줄 통찰 (One-line insight)
`text-align` controls horizontal alignment and `vertical-align` controls vertical alignment of content inside `<th>` and `<td>` cells. [S1]

## 🧠 핵심 개념 (Core concepts)
- **`text-align` = horizontal** — the CSS `text-align` property is used to set the horizontal alignment of the content in `<th>` or `<td>`. [S1]
- **`vertical-align` = vertical** — the CSS `vertical-align` property sets the vertical alignment (like top, bottom, or middle) of the content in `<th>` or `<td>`. [S1]
- **Defaults for headers vs data** — by default, the content of `<th>` elements is center-aligned and the content of `<td>` elements is left-aligned. [S1]
- **Default vertical alignment** — by default, the vertical alignment of the content in a table is middle (for both `<th>` and `<td>` elements). [S1]

## 🧩 추출된 패턴 (Extracted patterns)
- **Horizontal values** — `text-align` accepts `left` (aligns text to the left), `right` (aligns text to the right), and `center` (centers the text). [S1]
- **Vertical sizing pairing** — to make a vertical alignment visible, give the cell a `height` and then set `vertical-align` (e.g. `bottom`). [S1]

## 📖 세부 내용 (Details)
**Horizontal Alignment**
The CSS `text-align` property is used to set the horizontal alignment of the content in `<th>` or `<td>`. Property values: [S1]
- `left` — aligns the text to the left
- `right` — aligns the text to the right
- `center` — centers the text

**Note:** By default, the content of `<th>` elements is center-aligned and the content of `<td>` elements is left-aligned. [S1]

Center the content of `<td>` elements: [S1]
```css
td {
  text-align: center;
}
```

Left-align the content of `<th>` elements: [S1]
```css
th {
  text-align: left;
}
```

**Vertical Alignment**
The CSS `vertical-align` property sets the vertical alignment (like top, bottom, or middle) of the content in `<th>` or `<td>`. [S1]

**Note:** By default, the vertical alignment of the content in a table is middle (for both `<th>` and `<td>` elements). [S1]

The example below sets the vertical text alignment to bottom for `<td>` elements: [S1]
```css
td {
  height: 50px;
  vertical-align: bottom;
}
```

The source illustrates these rules with sample data tables containing Firstname/Lastname/Savings columns (e.g. Peter Griffin / $100, Lois Griffin / $150, Joe Swanson / $300). [S1]

## 🛠️ 적용 사례 (Applied in summary)
