What is a Row? What is a Column?

Updated on May 11, 2026

This article will help you get familiar with the concepts of rows and columns.

What is a Row? What is a Column?

Rows in the document model of RadSpreadProcessing are groups of cells that are on the same horizontal line. Each row is identified by a number. For example, the first row has an index 1, the second – 2, and the last – 1048576.

Similarly, a column is a group of cells that are vertically stacked and appear on the same vertical line. Columns in RadSpreadProcessing are identified by a letter or a combination of letters. For example, the first column is called A, the second – B, and the last column is XFD.

Row Height

Rows offer several approaches for determining their height:

OptionDescription
Default HeightEach row has a default height of 20. When the row does not have an explicitly set height, it appears with its default height.
HeightAllows you to make a given set of rows appear with a fixed height.
Auto FitSets the height of a specific row based on the content of all cells in the row. The height is determined by the cell with the tallest content.

Similarly, columns expose several ways to set their width:

OptionDescription
Default WidthEach column has a default width of 65. When the column does not have an explicit width set, it appears with its default width.
WidthAllows you to make a given set of columns appear with a fixed width.
Auto FitSets the width of a specified column based on the content of all cells in the column. The width is determined by the cell with the widest content.

More information about setting row's height and column's width is available in the Resizing Rows and Columns article.
