Write data in existing data row

Hi,
I have data table with few colums. Some of the colums already have values. In a loop, I need to write values to specific columns which is empty. Is there a way to access the table fields directly? Or any activities to do it?
P.S. table not from excel and no need to write it there

Hi @dariya.ashchepkova are you using a for each loop? Or perhaps even a for each row loop?

Hi @Jacqui_M
i’m using for each row loop

loop row first and then loop column
foreach the type change to DataColumn.

Thanks a lot, it works
The only thing i can’t assign string value to column, got error (on screenshot)

Correct assign is :
row(column.ColumnName) = “dddd”

you have to Foreach row in dataTable first.
The error maybe not find row

@dariya.ashchepkova

Refer my post above, check the comments also written properly follow them, so in your error first do foreach datatable within that do a foreach datacolumns

I have it, on screenshot you see nested sequence

I have for each row and nested for each datacolumn, on screenshot you see nested sequence
so i don’t think it is the reason of error
