How to Set Cell Border and Alignment

by Chaknith Bin

In Excel, cell borders are lines or borders that can be applied to individual cells or groups of cells, while text alignment refers to the positioning of text within a cell both vertically and horizontally.

With IronXL, you can enhance data visualization, improve readability, and create professional-looking spreadsheets by customizing border styles, thickness, colors, and aligning text to better present your data.

Set Cell Border and Alignment Example

Customize the appearance of a selected cell, column, row, or range by adding a border using the TopBorder, RightBorder, BottomBorder, and LeftBorder properties. Choose from various styles available in the IronXL.Styles.BorderType enum. Explore all available border types to find the perfect match.

For precise text alignment, adjust the HorizontalAlignment and VerticalAlignment properties in Style to achieve the desired layout. Utilize the IronXL.Styles.HorizontalAlignment and IronXL.Styles.VerticalAlignment enum to set the desired alignment. Discover all available alignment types to present your data flawlessly.

Border Color

By default, the border color is black, but you can customize it to any color available in the Color class or use a Hex color code. To set the border color, you can use the Color property with the desired color or Hex code. Additionally, the Color property allows you to retrieve the color of the border.

// Set cell border color
workSheet["B2"].Style.LeftBorder.SetColor(Color.Aquamarine);
workSheet["B2"].Style.RightBorder.SetColor("#FF7F50");

Border Lines & Patterns

In total, there are six border line positions, each offering a variety of patterns or types. These positions include top, right, bottom, left, as well as diagonal lines moving forward, backward, and both.

using IronXL;
using IronXL.Styles;

WorkBook workBook = WorkBook.Create();
WorkSheet workSheet = workBook.DefaultWorkSheet;

workSheet["B2"].StringValue = "Top";
workSheet["B4"].StringValue = "Forward";

// Set top border line
workSheet["B2"].Style.TopBorder.Type = BorderType.Thick;

// Set diagonal border line
workSheet["B4"].Style.DiagonalBorder.Type = BorderType.Thick;
// Set diagonal border direction
workSheet["B4"].Style.DiagonalBorderDirection = DiagonalBorderDirection.Forward;

Private workSheet("B2").StringValue = "Top"

' Set top border line
Private workSheet("B2").Style.TopBorder.Type = BorderType.Thick

' Set diagonal border line
Private workSheet("B4").Style.DiagonalBorder.Type = BorderType.Thick
' Set diagonal border direction
Private workSheet("B4").Style.DiagonalBorderDirection = DiagonalBorderDirection.Forward

Alignment Types

Discover the full range of alignment options offered by IronXL in the illustration below:

HorizontalAlignment Enumeration:

• General: General-aligned horizontal alignment. Text data is left-aligned. Numbers, dates, and times are right-aligned, and Boolean types are centered. Changing the alignment does not affect the data type.
• Left: Left-aligned horizontal alignment, even in Right-to-Left mode. Aligns contents at the left edge of the cell. If an indent amount is specified, the cell's contents are indented from the left by the specified number of character spaces.
• Center: Centered horizontal alignment, meaning the text is centered across the cell.
• Right: Right-aligned horizontal alignment, meaning that cell contents are aligned at the right edge of the cell, even in Right-to-Left mode.
• Fill: The value of the cell is filled across the entire width. If adjacent cells to the right also have the same fill alignment, they will be filled as well. Additional rules:
  • Only whole values can be appended, not partial values.
  • The column will not be widened to 'best fit' the filled value.
  • If appending an additional occurrence of the value exceeds the boundary of the cell's left/right edge, it will not be added.
  • The display value of the cell is filled, not the underlying raw number.
• Justify: Justified (flush left and right) horizontal alignment. Applies wrap text to the cell and ensures that each line aligns the first word with the left edge and the last word with the right edge of the cell (except for the last line).
• CenterSelection: Horizontally centers the content of the left-most cell to the center across multiple cells. It visually appears similar to merging cells, but without actually merging them. Using this option helps prevent potential issues that may arise from merged cells.
• Distributed: Each 'word' in each line of text inside the cell is evenly distributed across the cell's width, with flush right and left margins. If there is an indent value to apply, both the left and right sides of the cell are padded by the indent value.

VerticalAlignment Enumeration:

• None: The default alignment.
• Top: Aligns content at the top of the cell.
• Center: Vertically centers the content within the cell.
• Bottom: Aligns content at the bottom of the cell.
• Justify: Distributes the lines of text evenly across the cell's height, with flush top and bottom margins. Works similarly to horizontal justification by wrapping text and adjusting the spaces between lines to occupy the entire row's height.
• Distributed: Distributes each 'word' in each line of text evenly across the cell's height, with flush top and bottom margins in horizontal text direction. In vertical text direction, it behaves exactly as distributed - horizontal alignment, evenly distributing the lines of text from top to bottom.
