单元格级别绑定

SpreadJS 支持单元格级别绑定,你可以将数据源的数据绑定到单元格上。

你必须创建一个单元格级别绑定的数据源, 然后使用 setBindingPath 方法来设置绑定路径到指定的单元格,并将数据源设置到表单上。例如: 你可以使用 getBindingPath 方法来获取指定单元格的绑定信息。
<template> <div class="sample-tutorial"> <gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread"> <gc-worksheet> <gc-column :width=120></gc-column> <gc-column :width=120></gc-column> <gc-column :width=120></gc-column> </gc-worksheet> </gc-spread-sheets> <div class="options-container"> <div class="option-row"> <label style="background-color:#F4F8EB;">Select one of the gray cells to get its binding.
