How to Change Border Colors in PowerPoint Table: Step-by-Step Formatting Guide

Tables in PowerPoint don’t have to look boring. I’ve seen presentations where a simple border color change made the data pop and the audience actually pay attention.

This isn’t about fancy design skills—it’s about knowing where to click. The Table Design tab holds the key, and once you find it, changing borders takes less than a minute.

You’ll get crisp, professional-looking tables that guide the eye exactly where you want it. Works in PowerPoint 2016 and newer, including the web version.

No special tools, no workarounds. Just a straightforward method that’s saved me from dull slides more times than I can count.

What Youll Need

Instructions

Here’s the procedure I follow to get professional-quality table borders every time.

Click anywhere inside the table to select it. You’ll see the Table Design tab appear in the ribbon. I always double-check that the entire table is selected by looking for the small square handles at each corner.

In the Table Design tab, locate the Borders group. Click the small arrow in the bottom-right corner of this group to open the Borders and Shading dialog box. This is where all border customization happens.

In the Borders tab of the dialog box, first select your border style from the left panel. You can choose individual borders (top, bottom, left, right) or apply to all borders at once. I typically start with All Borders for consistency.

Next, click the Color dropdown and select your preferred color. If the exact shade isn’t available, choose More Colors to access the full palette. The selected color appears in the preview box immediately.

Border color alone might not be enough for visibility. Use the Width dropdown to adjust thickness. For a subtle look, 1 pt works well. For emphasis, try 2.25 pt or 3 pt. The preview shows changes in real time.

Here’s the thing—thicker borders can make a table look cluttered. I’ve found that using a slightly thicker border for outer edges (like 1.5 pt) and thinner for inner lines (like 0.75 pt) creates a balanced, professional appearance.

To change borders for specific cells, first select those cells by clicking and dragging. Then open the Borders and Shading dialog as before. The changes will now apply only to your selection.

For more complex designs, use the Borders dropdown in the ribbon to apply predefined border styles to selected cells. The Inside Horizontal Border and Inside Vertical Border options are particularly useful for maintaining consistency across large tables.

After applying changes, zoom out to 80-100% to check the overall appearance. Colors might look different at various zoom levels. If the borders appear too faint, increase the width or darken the color.

If you notice inconsistencies, check that you’ve selected the correct borders in the preview diagram. It’s easy to accidentally apply changes to the wrong edges. The diagram clearly shows which borders will be affected before you click OK.

Tips and Common Mistakes

These practical insights will help you avoid frustration when customizing your table borders.

The Selection Trick: In Step 1, always verify your entire table is selected by checking for those small square handles at each corner. I’ve accidentally formatted only one cell more times than I’d like to admit—it’s an easy mistake to make when you’re moving quickly.

Color Consistency: When choosing colors in Step 2, test your selection at different zoom levels (like the 80-100% mentioned in Step 5). What looks perfect at 100% might disappear or clash at lower zoom levels, especially in presentations viewed on projectors.

Width Strategy: For Step 3, resist the urge to go too thick with your borders. While 2.25 pt or 3 pt can add emphasis, I’ve found that anything above 1.5 pt for outer edges can make your table look bulky. Stick to the suggested 1 pt for inner lines to keep it clean.

Preview Habit: Always use the preview diagram in the Borders and Shading dialog before clicking OK. It’s saved me countless times from applying borders to the wrong edges, which is surprisingly easy to do in Step 4 when working with specific cells.
