Print.js

内部二开功能

理论实现

1. 复杂表头 开发中
2. 合并单元格 开发中

单元格合并规则：

行合并：

注意：需要将被合并的单元格设置为 undefined

[
  {
    [key]: {
      span: 2,
      type:'colspan',
      data: '132123'
    }
  }
]

列合并：

[
  {
    [key]: {
      span: 3,
      type:'rowspan',
      data: ['123', '123123', '123123']
    }
  }
]

示例数据:

const someJSONdata = [
  {
    name: 'John Doe', email: ['[email protected]', '[email protected]'], test: {
      type: 'rowspan',
      span: 3,
      data: ['123', '123123', '123123', '123123123']
    }, phone: '111-111-1111',
  },
  {
    name: 'John Doe', email: '123123123', test: 123123123, phone: '111-111-1111'
  },
  {
    name: 'John Doe', email: '123123123', test: {
      span: 2,
      type: 'colspan',
      data: '123123123'
    },
  },
  {
    name: { 
      span: 2,
      type: 'colspan',
      data: '132123'
    },
    test: {
      type: 'rowspan',
      span: 4,
      data: ['123', '123123', '123123', '123123123']
    },
    phone: '111-111-1111',
  },
];
