如何获取表格总行数和内容实际高度

问题描述

如何通过API，从表格实例中获取当前表格总行数和内容实际高度

解决方案

table实例中colCount和rowCount属性，可以获取当前表格的行列数量
table示例提供方法getAllRowsHeight和getAllColsWidth，可以获取当前表格内容的总列宽和总行高

代码示例

const tableInstance = new VTable.ListTable(container, option);

console.log(tableInstance.colCount);
console.log(tableInstance.rowCount);
console.log(tableInstance.getAllRowsHeight());
console.log(tableInstance.getAllColsWidth());</br>

完整示例代码（可以粘贴到编辑器上尝试一下）：

let  tableInstance;
  fetch('https://lf9-dp-fe-cms-tos.byteorg.com/obj/bit-cloud/VTable/North_American_Superstore_data.json')
    .then((res) => res.json())
    .then((data) => {

const columns =[
    {
        "field": "Order ID",
        "title": "Order ID",
        "width": "auto"
    },
    {
        "field": "Customer ID",
        "title": "Customer ID",
        "width": "auto"
    },
    {
        "field": "Product Name",
        "title": "Product Name",
        "width": "auto"
    },
    {
        "field": "Category",
        "title": "Category",
        "width": "auto"
    },
    {
        "field": "Sub-Category",
        "title": "Sub-Category",
        "width": "auto"
    },
    {
        "field": "Region",
        "title": "Region",
        "width": "auto"
    },
    {
        "field": "City",
        "title": "City",
        "width": "auto"
    },
    {
        "field": "Order Date",
        "title": "Order Date",
        "width": "auto"
    },
    {
        "field": "Quantity",
        "title": "Quantity",
        "width": "auto"
    },
    {
        "field": "Sales",
        "title": "Sales",
        "width": "auto"
    },
    {
        "field": "Profit",
        "title": "Profit",
        "width": "auto"
    }
];

const option = {
  records:data,
  columns,
  widthMode:'standard'
};
tableInstance = new VTable.ListTable(document.getElementById(CONTAINER_ID),option);
window['tableInstance'] = tableInstance;

console.log(tableInstance.colCount);
console.log(tableInstance.rowCount);
console.log(tableInstance.getAllRowsHeight());
console.log(tableInstance.getAllColsWidth());
    })</br>
