How to understand "Detect type of resulting columns" in node"row to column header"

[skozer]

Check two status. one with this option. while the other unchecked.
Output tables for both upper and lower keep the same result.
How to understand this?

Hi @skozer and welcome back to the kNIME Community Forum,

If you have only 1 row as column names, then yes, there would be no difference since there is no data available to detect the column types. But if you have some data rows in the table as well, then checking this option will give you the table with proper column types based on the available data.

Thanks Armin.
You are telling things will be different while multi-rows is enabled.

My table includes multi-rows, which shares same parameter type in each column. Based on this setting, it doesn’t feedback any change by enabling or disabling “detect column types”.

An example input data is:

|column1(s)|column2(I)|column3(s)|column4(D)|
|A|1|D|11.1|
|B|2|E|12|
|C|3|F|13|
