Using a loop to write to the same excel file within different sheets

I currently have a table with 4 columns, one of which being an identifier. The end goal is to output each group of like identifiers to a new sheet within the same excel file. I’m relatively new to KNIME so my understanding of loops isn’t great. My intuition tells me it’s possible to put a row filter within a loop, and then have it iterate through the table based on the identifier variable. Again, I’m relatively new to KNIME so my knowledge of flow variables also isn’t great. I’ve included a screenshot of the input table I wish to split up (by column 1 “LDGR_CO”). Any help would be greatly appreciated.
