By the end of this lesson you will be able to enhance a spreadsheet by applying:
Text colour
Cell (background) colour
Bold, underline and italic text styles
Shading (patterned fill)
1. Why enhance a spreadsheet?
Formatting makes data easier to read, highlights important information and gives a professional appearance. Consistent use of colour and style also helps when presenting results to others.
2. Text Formatting
Text formatting changes the appearance of the characters inside a cell without affecting the cell’s background.
Select the cell or range of cells you wish to format.
Use the toolbar buttons or keyboard shortcuts to apply the required style.
2.1 Available text styles
Style
Toolbar icon description
Windows shortcut
macOS shortcut
Bold
Letter “B” in a solid box
Ctrl + B
Command + B
Italic
Letter “I” slanted
Ctrl + I
Command + I
Underline
Letter “U” with a line beneath
Ctrl + U
Command + U
Text colour
Letter “A” with a colour bar
Alt + H, FC (Excel) – varies by program
Option + Command + C (varies)
3. Cell (Background) Colour
Cell colour fills the entire cell background and can be used to group related data or draw attention to key figures.
Select the cell or range.
Click the “Fill colour” button on the toolbar (usually a paint‑bucket icon).
Choose a colour from the palette.
4. Shading (Patterned Fill)
Shading adds a pattern (e.g., stripes or dots) over the cell background. It is useful when printing in black‑and‑white or when colour printing is unavailable.
Select the target cells.
Open the “Format Cells” dialog (right‑click → Format Cells or Ctrl + 1).
Navigate to the “Fill” or “Pattern” tab.
Choose a pattern and, optionally, a foreground and background colour.
5. Practical Example – Applying Multiple Enhancements
The table below shows a simple sales report before and after formatting.
Item
Units Sold
Revenue (£)
Notes
Widget A
120
1,200
Target met
Widget B
85
850
Below target
Widget C
150
2,250
Best performer
Formatting steps for the example:
Make the header row bold and give it a dark grey cell colour.
Set the “Revenue (£)” column text to bold and colour it dark green.
Apply a light yellow cell colour to any cell containing the word “Best”.
Underline the “Target met” note to highlight achievement.
Use a light blue shading pattern for the entire “Units Sold” column to differentiate it from monetary values.
