In many situations, you may need to merge cells together for best results. Please see the steps below to merge and center cells:
Step 1: Select the cells or area you need to merge and center, e.g., A3-A5;
Step 2: Click the "Home" tab from the Ribbon;
Step 3: Click the command "Merge&Center" in the "Alignment" section;
Step 4: A reminding warning "Merging cells only keep the upper-left value and discard other values" will appear, click "OK" if you are ok;
Step 5: All the cells you selected (A3 - A5 in this example) are now in one cell.
Please note that when merge and center multiple cells with values, only keeps the upper-left value and discards other values!
