This article explains why your cell values are not correctly aligned in your Awesome Table apps.
Explanation
Awesome Table only sees the data-type (but not the formatting) in your spreadsheet datasource. Numeric values are automatically right-aligned while plain text values are left-aligned.
Recommendation
If you want to center align your numeric values, convert them to plain text first, then apply the center align property on the pertinent columns' CSS selector. Learn more: Apply style to specific columns.
warning Filters designed for numeric values will not work when numbers are converted to plain text.
