Merging Cells with Continental Nodes

There has been no title set for this workflow's metadata.

Demo workflow for merging cells in columns where the String values of the columns have been repeated

Create "control table" based on location of empty cells which follow non-empty cells in each column Add empty row as first row of control table, and then pass the whole table to the "Control TableGenerator" Get the distinct set of "merge tags" that we have generated. I have been lazy and generated a merge tag for every cell, even ifit is a single cell Create the XLSX file and write the data to it. Modify the file path with the addition of a suffix to the file name,and then apply formatting to that file using the XLS Formatter (apply) node Apply the XLS Continental formatting to the merge tags. State that the merge tag represents a cell to be merged, and also specify that on mergeing, the verticalalignment is to be "centred".
