AutoFit Rows and Columns

Microsoft Excel lets users auto size the width and height of cells according to its content. This feature is also available through Aspose.Cells for Python via .NET so developers can auto size the dimensions of a cell at runtime.

Auto Fitting

Aspose.Cells for Python via .NET provides a Workbook class that represents a Microsoft Excel file. The Workbook class contains a worksheets collection that allows access to each worksheet in an Excel file. A worksheet is represented by the Worksheet class. The Worksheet class provides a wide range of properties and methods for managing a worksheet. This article looks at using the Worksheet class to autofit rows or columns.

AutoFit Row - Simple

The most straight-forward approach to auto-sizing the width and height of a row is to call the Worksheet class auto_fit_row method. The auto_fit_row method takes a row index (of the row to be resized) as a parameter.

How to AutoFit Row in a Range of Cells

A row is composed of many columns. Aspose.Cells for Python via .NET allows developers to auto-fit a row based on the content in a range of cells within the row by calling an overloaded version of the auto_fit_row method. It takes the following parameters:

• Row index, the index of the row about to be auto-fitted.
• First column index, the index of the row’s first column.
• Last column index, the index of the row’s last column.

The auto_fit_row method checks the contents of all the columns in the row and then auto-fits the row.

How to AutoFit Column in a Range of Cells

A column is composed of many rows. It is possible to auto-fit a column based on the content in a range of cells in the column by calling an overloaded version of auto_fit_column method that takes the following parameters:

• Column index, the index of the column about to be auto-fitted.
• First row index, the index of the column’s first row.
• Last row index, the index of the column’s last row.

The auto_fit_column method checks the contents of all rows in the column and then auto-fits the column.

How to AutoFit Rows for Merged Cells

With Aspose.Cells for Python via .NET it is possible to autofit rows even for cells that have been merged using the AutoFitterOptions API. AutoFitterOptions class provides auto_fit_merged_cells_type property that can be used to autofit rows for merged cells. auto_fit_merged_cells_type accepts AutoFitMergedCellsType enumerable which has the following members.

• NONE: Ignore merged cells.
• FIRST_LINE: Only expands the height of the first row.
• LAST_LINE: Only expands the height of the last row.
• EACH_LINE: Only expands the height of each row.

You may also try to use the overloaded versions of auto_fit_rows & auto_fit_columns methods accepting a range of rows/columns and an instance of AutoFitterOptions to auto-fit the selected rows/columns with your desired AutoFitterOptions accordingly.

The signatures of the aforesaid methods are as follow:

1. auto_fit_rows(start_row, end_row, options options)
2. auto_fit_columns(first_column, last_column, options)

Important to Know

If a cell is merged then the AutoFit methods will not be applied, which is the same behavior as in Microsoft Excel. You can get around this by using the auto filter API. Moreover, if the text in a cell is wrapped, the auto_fit_column method will not be applied either. Another thing you need to know is that the AutoFit methods are time-consuming. So, you should call these methods as seldom as possible to ensure the efficiency of your application.
