Repeat Excel Rows & Columns, Code Examples

from ironxl import * # Load existing spreadsheet workbook = WorkBook.Load("sample.xlsx") worksheet = workbook.DefaultWorkSheet # Set repeating rows for row(2-4) worksheet.SetRepeatingRows(1, 3) # Set repeating columns for column(C-D) worksheet.SetRepeatingColumns(2, 3) # Set column break after column(H). Hence, the first page will only contain column(A-G) worksheet.SetColumnBreak(7) # Save changes with repeating rows and columns workbook.SaveAs("repeatingRows.xlsx")

Repeat Excel Rows & Columns

When Excel spreadsheets span multiple printed pages, readability improves significantly when column or row titles are repeated at the top or left of every page. These are called Repeating Rows and Columns (also known as Header Rows and Columns) in Excel. IronXL for Python enables this feature with just a few lines of code.

`SetRepeatingRows(startRow, endRow)`

This method sets repeating rows. For example, calling worksheet.SetRepeatingRows(3, 4) repeats rows 4 and 5 on every printed page.

`SetRepeatingColumns(startColumn, endColumn)`

This method sets repeating columns. For example, calling worksheet.SetRepeatingColumns(0, 2) repeats columns A through C on every printed page.

Both methods use zero-based indexing, where column 0 corresponds to "A" and row 1 corresponds to row 2 in Excel. When SetRepeatingRows and SetRepeatingColumns are used together, the repeating rules applied to each page depend on its position relative to the first page.

Pages that extend to the right of the first page will have the repeating column rule applied only. Pages that extend below the first page will have the repeating row rule applied only. Pages located in the inner area of the print range will have both rules applied simultaneously.
