About loop output datatable

9221016ytl

I want to output the classification of the datatable in a loop, and output the corresponding datatable article list according to the classification, that is, the left cell is the classification, and the right cell is the article list (take the first five). Tried many times, but the page structure is not neat, I don't know how to achieve output and maintain the format? Hope you master

Try using table
Then insert the information into the table yourself

I just use TABLE, but the datatable data rows [i] and i in TABLE are all manually assigned. I would like to ask you if there is a way to associate the two datatables and output them automatically. For example, if I want to cycle the row output classification, Nest the TABLE loop in the second column of the row where the loop comes out to output the article title of this class.

Relate yourself, not all code is written by someone, then the programmer profession does not exist

Halo, I learned this for two months, and I don’t understand a lot, so I asked everyone, please don’t hit me, let’s help the newcomer

You can try it with datatable.select(...).
for(int i = 0;i< datatable1.rows.count;i++)
{
  ...
  datarows []rs = datatable2.select("xxx = "+ datatable1.row[i]["??"].tostring());
  ...
}
Do not know whether you can meet your requirements by using a similar method.

Sorry, upstairs, mine uses two conditions to filter out categories and articles respectively. How can I relate that?

Associate with Sql statement

It can be achieved with the right join statement. If such a table set structure can be obtained on the data source, try to process it on the data source.
