How to extract data into selected column and keep adding another column?

Hi, I am trying to get data that extract from web and place them into each column that I prepare. (“30122564”, 17012565", “01022565”)
However, every time I extract the data it end up adding new column. (“(Day)(0).ToString”) Also it only get the last result from the list that.

Here is example

I want the data in column “(Day)(0).ToString” (10 rows) to be in column “30122564” and after that repeat for the next column “17012565” (another 10 rows).

Objective

  1. To put all data that extract from web in the column of the date that has been add before hand.
  2. repeat the process by place next data in the next column.

Thank you in advance.
