如何将数据表转换为HTML格式字符串

本文介绍了如何将数据表转换为HTML格式字符串的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有两个数据表datatable1& datatable2。

datatable1包含3行标题

I have two datatables datatable1 & datatable2.

datatable1 contains heading with 3 rows

SL.No CutomerId CustomerName PaymentId  
1,12345,ABC,99999 
2,23456,FGH,88888 
3,54321,MNB,77777

datatable2包含2行标题

datatable2 Contains heading with 2 rows

BankRef BankName PaymentId Address City  
ref12, HSBC, 99999, Street11, NY 
ref13, HSBC, 88888, Street11, NY

我的要求是组合两个表格，只有html字符串格式的选定列如下（标题和行）。这是来自datatable2&的3列。来自datatable1的1列。

My requirement is combination both tables with only selected columns in html string format as below(heading & rows). That is 3 columns from datatable2 & 1 column from datatable1.

BankRef BankName CustomerName PaymentId
ref12,   HSBC,    ABC,       99999

如何实现这一目标。
