Hello pbishop,
The misalignment in your table headers imay be likely due to the default alignment settings in Amazon QuickSight. To fix this alignment issue, you can customize the header text alignment in the Properties pane.
Assuming the visual is table chart - please refer here
First, select your table visual and open the Format visual menu - please refer here
Then, in the Properties pane, choose Headers.
For header text alignment, you can choose a horizontal alignment icon - options include left alignment, center alignment, right alignment, or automatic alignment.
For pivot tables, you can separately adjust alignment for both column headers in the Columns section and row headers in the Rows section.
Unfortunately, it’s not currently possible to set different alignment behaviour’s for individual columns in a table - any alignment changes would apply to the whole table. see old post here
You can also adjust vertical alignment by choosing a vertical alignment icon (top, middle, or bottom.
Additionally, if your headers contain text that’s too long to fit, you can select the “Wrap text” option, though you may need to increase header height as well.
Hope this helps.
Cheers,
Deep
