The background of a cell in a spreadsheet or table is called the "cell fill." It is the color or pattern applied to the background of the cell to differentiate it from other cells. It can help with organization and visual appeal in the document.

Using your HTML editor software, open a NEW document. (NOTE: I use Kompozer free HTML editor.) Select TABLE and Insert Select - "One Cell" Table format Click on the Table to select it Select TABLE and Table Cell Properties Select Table Tab Select the Height and Width you desire either as % or pixel for the Table Select Table Alignment and choose Center Select Background Color and choose the color for the Table (i.e. white) Click OK Click Apply Click OK Select FORMAT > Page Colors and Background Select Use Custom Colors Then choose the color for the background that will appear behind your Table and make any changes you want to the font and link colors for within your Table. Click OK You will now have a centered webpage that is white (or whatever color you choose) that has a contrasting background behind it. NOTE: If you want to have sections within your centered webpage (Table), you just click inside the Table and insert another Table into it. Then set the size and color of the second Table the same as above.
If you want to make a cell stand out, you can make the text bold, change the font and font size, make the cell italic, change the foreground or background color, and use borders.

The order of precedence for table formatting typically follows this hierarchy: first, cell formatting (including font size, color, and alignment) takes precedence, then row formatting (such as height and background color), followed by column formatting (width and styles), and finally, the overall table formatting (borders, shading, and general layout). In cases where specific styles conflict, the most specific formatting (cell settings) usually overrides more general settings (table or row styles). This ensures that individual cell attributes are prioritized over broader table or row configurations.

When you change the color of the fill in a cell you are changing its format. This action applies to Microsoft Excel.
Cell formatting in Excel allows you to define how the cell contents should appear. Some examples of formatting are bold, italics, character color, cell background color, currency, time, etc.
The color change inside the cell could be due to a chemical reaction that altered the properties of the compounds present, causing them to absorb and reflect light differently. This change in the molecular structure or composition can result in a visible change in color.
To change a cell color in most spreadsheet applications like Microsoft Excel or Google Sheets, you should select the "Format" menu. From there, choose "Cell" or "Cell color" options, and then you can pick your desired color. Alternatively, you can often find a paint bucket icon in the toolbar for quick access to fill color options.
