Overview

Column headers are gray-colored rows used to label each column or group of columns. By default, these headers are populated with letters in alphabetical order.

To reflect the type or category of data in a particular column, give it a custom name and then display it in a column header. For example, instead of letters as labels such as A, B, C, ... name them ID, Full name, Country, ....

Default headers

Setting the colHeaders option to true enables the default column headers as shown in the example below:

Customize column headers

You can align the text in the header label with the headerClassName option. Setting it to htLeft, htCenter, or htRight will align the header labels to the left, center, or right, respectively.

You can also set the alignment for a specific column by using the columns option.
