Cell fill color bleeds into adjacent cells in Excel when the file is viewed in Web browser

When you format a column to the end with one fill color in Microsoft Excel, but some cells above the fill have no background, and then you save the file as a Web page, the fill color will show behind data in the unformatted cells.

This problem is caused by a limitation of the HTML that Excel writes out.

To work around this problem, use any of the following methods.

Method 1: Do not format any unnecessary or unused cells

Method 2: Format any cells with data with a white fill color

To do this, follow these steps:

1. Select the cell(s) you want to have a white fill color.
2. On the Format menu, click Cells.
3. On the Patterns tab, click the white color from the Color palette and click OK.

Method 3: Define the default style for unformatted cells

Define the default style for unformatted cells to have a background fill color of white. To do this, follow these steps:

1. On the Format menu, click Style.
2. In the Style dialog box, click Modify.
3. On the Patterns tab, click the white color on the Color palette, and click OK twice.
