How can I vertically center text in an AG Grid cell?

To vertically center text within an AG Grid cell, you can use CSS. AG Grid provides several ways to customize cell rendering, and CSS is the most common approach for styling.

Here's how you can achieve vertical centering:

1. Using `cellStyle` Property:

- The `cellStyle` property in the column definition allows you to apply CSS styles directly to the cell. You can use CSS properties like `display: flex`, `align-items: center`, and `justify-content: center` to achieve vertical and horizontal centering.

2. Example Code:

const columnDefs = [
  {
    headerName: "Name",
    field: "name",
    cellStyle: {
      display: 'flex',
      alignItems: 'center',
      justifyContent: 'center',
    },
  },
   // Other column definitions
];

- In this example, the `cellStyle` object is applied to the "Name" column. The `display: flex` property turns the cell into a flex container. `alignItems: center` vertically centers the content, and `justifyContent: center` horizontally centers the content. If you only need vertical centering, you can omit `justifyContent: center`.

3. Using a CSS Class:

- Alternatively, you can define a CSS class and apply it to the cell using the `cellClass` property. This approach is useful if you want to reuse the same styling across multiple columns.

4. Example CSS Class:

.ag-vertical-center {
  display: flex;
  align-items: center;
  justify-content: center;
}

5. Applying the CSS Class:

const columnDefs = [
  {
    headerName: "Name",
    field: "name",
    cellClass: 'ag-vertical-center',
  },
   // Other column definitions
];

- Here, the `ag-vertical-center` class is applied to the "Name" column using the `cellClass` property.

6. Considerations:

- Ensure that the AG Grid's CSS is loaded correctly and that your custom CSS is applied after AG Grid's default styles. You might need to adjust the specificity of your CSS rules if they are not being applied correctly.

By using either the `cellStyle` property or a custom CSS class with `cellClass`, you can easily vertically center text within AG Grid cells. Choose the method that best suits your project's needs and coding style.
