I need to wite a datatable which is empty but I need to maintain the headers of the datatable at the top.
How to write the headers at the top also if the datatable is empty?
You should use build data table activity. Then you can use write range activity which add headers property enabled. That could work i guess.
@CamiCat Get Count Of the table if Zero then Use IF else and Write the table you created using Build DataTable else the original table
Whether you have a datatable obtained by any means with or without data like either obtained from data scrapping or using build datatable activity, whenever we use a WRITE RANGE activity we need to enable ADD HEADERS property and in the range mention as “A1” so that the headers will be included and also the will be included at the top that is the first row of the excel at all situations
Hope this would help you
If you are using Excel - Write Range :
Check Add Headers in the Write Range Activity
If you are using Workbook - Write Range Activity :
If you want to write the DataTable even if it is Empty follow below simple Method.
- Build a Data Table with your required Columns and Add first row with same column names
- Don’t use Add Headers in Write Range Activity while writing to Workbook.
Note : This is for Writing Headers even DataTable is empty. if you want DataTable row count , It will give one extra row count, As we added Header as row.
Solution : Add Headers.xaml (6.6 KB)
Thank you so much @Ramprasad.
I’ll try and let you know as soon as possible.
May I know why do we need to add the header again in the first row of the datatable explicitly
Rather we can just do with a simple check box ADD HEADERS
Because this is fine if we have a single data entry but what if there are two or more than five
We won’t be able to explicitly add a row same as headers in all the datatable as a first row
If ADD HEADERS is enabled it will automatically the first row as headers right @CamiCat
Kindly elaborate that @Ramprasad
Yes, You are correct , If we are using Write Range with Excel Application Scope, it will Add Headers even there is no Data in the DataTable. In the Workbook Write Range Activity , if there is no data in the DataTable , it will not add headers.
Thank you so much @Palaniyappan,
is it also possible to add an empty row (how to initialize an empty row) and then wirte range in the Excel?
Thank you so much,
Yah of course
In add data row activity mention this in the datarow property
Yourdatatablename.NewRow and in the datatable mention the datatable name
The we can pass that as input to write range activity
