Apply Shading to Alternate Rows and Columns with Conditional Formatting

Aspose.Cells APIs provide the means to add & manipulate conditional formatting rules for the Worksheet object. These rules can be tailored in a number of ways to get the desired formatting based on conditions. This article will demonstrate the use of Aspose.Cells for Java API to apply shading to alternate rows & columns with the help of conditional formatting rules and Excel’s built-in functions.

Apply Shading to Alternate Rows & Columns using Conditional Formatting

This article makes use of Excel’s built-in functions such as ROW, COLUMN & MOD. Here are brief details of these functions for a better understanding of the code snippet provided below.

• ROW() function returns the row number of a cell reference. If the reference is omitted, it assumes that the reference is the cell address in which the ROW function has been entered.
• COLUMN() function returns the column number of a cell reference. If the reference is omitted, it assumes that the reference is the cell address in which the COLUMN function has been entered.
• MOD() function returns the remainder after a number is divided by a divisor, where the first parameter to the function is the numeric value whose remainder you wish to find and the second parameter is the number used to divide into the first parameter. If the divisor is 0, then it will return the #DIV/0! error.

Let us start writing some code to accomplish the goal with the help of Aspose.Cells for Java API.

The following snapshot shows the resultant spreadsheet loaded in the Excel application.

In order to apply shading to alternating columns, all you have to do is change the formula =MOD(ROW(),2)=0 to =MOD(COLUMN(),2)=0; that is, instead of using the row index, use the column index.
The resultant spreadsheet, in this case, will look like the following image.
