Table Alignment and Color Formatting in Campaigns

Table Alignment and Color Formatting in Campaigns

I have inserted tables into my campaign and the default is a left alignment.  The header formats to the left but the four rows below stick to the center.  When I click on table, row or cell properties it says these rows are to left but they are not. 

Also how do I custom color the header from the default pale yellow to a different color?

Grateful for your assistance,

Lisa
