elementui修改表格的line-height

### 调整 Element UI 表格组件中的 `line-height` 样式
为了调整 Element UI 中表格组件的行高 (`line-height`),可以通过自定义样式覆盖默认样式来实现。具体做法是在全局或局部范围内通过 CSS 或 SCSS 定义新的样式规则。
在给定的例子中,如果想要改变 `.el-table` 组件内的文本行距,则可以在 `<style>` 部分加入特定的选择器并设定所需的 `line-height` 值[^3]:
```css
<style>
/* 修改整个表格内单元格的 line-height */
.el-table td, .el-table th {
line-height: 2em !important;
}
</style>
```
上述代码片段展示了如何利用更具体的类选择器(即`.el-table td`, `.el-table th`),并通过增加 `!important` 来确保新设置能够生效,即使存在其他样式的优先级冲突情况也无妨。这里使用的 `2em` 是一个例子,实际应用时可以根据需求调整这个值到合适的大小。
另外一种方式是针对某个特定实例进行定制化处理,在模板里包裹一层带有唯一标识符 (class/id) 的 div,并在此基础上编写更具针对性的CSS规则:
```html
<template>
<div class="custom-line-height">
<el-table :data="tableData"></el-table>
</div>
</template>
<style scoped>
.custom-line-height /deep/ .el-table__row>.el-table-column--selection+.el-table-cell,
.custom-line-height /deep/ .el-table__row>.el-table-cell{
line-height: 1.8; /* 自定义行高等属性 */
}
</style>
```
此方法适用于希望仅影响单个页面上的某张表的情况;而 `/deep/` 关键字则用来穿透 Vue 单文件组件的作用域限制,使得内部元素也能被选中和修改其样式。
#### 注意事项
- 使用 `!important` 应谨慎对待,因为它可能会使未来的样式管理变得复杂。
- 如果项目采用的是预处理器如 SASS/SCSS ,记得按照相应语法书写样式声明。

Introduction
The R-loop, a three-stranded nucleic acid structure composed of an RNA:DNA hybrid and a displaced single-stranded DNA, plays versatile roles in many physiological and pathological processes. However, its controversial genomic localization and
incomplete understanding of its regulatory network raise great challenges for R-loop research. Here, we present R-loopBase to tackle these pressing issues by systematic integration of a huge amount of genomics and literature data. A reference set of human R-loop zones is computed
with confidence scores and detailed annotations (Search, Help and Download),
all of which can be visualized in well-annotated genomic context in a local genome browser (Browser). A list of 1,185 R-loop regulators is manually curated from PubMed literatures
and annotated with most up-to-date multi-omics data (Regulator).
We have also manually curated 24 R-loop regulators in mouse, 63 in yeast (saccharomyces cerevisiae) and 21 in Escherichia coli to facilicate R-loop research in these model organisms (Regulator).
We further deduce the functional relationship between individual R-loops and their putative regulators
(Regulator and Download). In total, we have generated billions of entries of functional annotations, which can be easily accessed in our
user-friendly interfaces (Help).
The regulator summary and genomic annotation of R-loop regions will be constantly updated along the research progress of field. You are welcome to contribute to updating R-loop regulators and related literatures (Regulator Updating System on Regulator page).
Any suggestions and feedbacks from you are also welcome
