如何从表格中的单元格获取值？

var table = document.getElementById("tableId"); // 获取表格元素
var row = table.rows[rowIndex]; // 获取指定行
var cell = row.cells[cellIndex]; // 获取指定列
var value = cell.innerHTML; // 获取单元格的值

import pandas as pd

data = pd.read_excel("table.xlsx")  # 读取Excel表格数据
value = data.iloc[rowIndex, columnIndex]  # 获取指定单元格的值

WebElement table = driver.findElement(By.id("tableId")); // 定位表格元素
WebElement cell = table.findElement(By.xpath("//tr[rowIndex]/td[cellIndex]")); // 定位指定单元格
String value = cell.getText(); // 获取单元格的值

SELECT columnName FROM tableName WHERE rowId = rowIndex AND columnId = columnIndex;

const tencentcloud = require("tencentcloud-sdk-nodejs");

// 创建API客户端实例
const client = new tencentcloud.yourServiceClient({
  credential: {
    secretId: "yourSecretId",
    secretKey: "yourSecretKey",
  },
  region: "yourRegion",
});

// 调用API接口获取表格中的单元格值
const params = {
  tableName: "yourTableName",
  rowId: "yourRowId",
  columnId: "yourColumnId",
};

client.getValue(params, (err, response) => {
  if (err) {
    console.error(err);
    return;
  }
  
  const value = response.value;
  console.log(value);
});
