Referencing this comment, you could do something like this to align the table to the center:

var X = myTable.MakeTags().replace(/^\<table/, "<table alignment=center");

On a side note, leading is measured in 10th's of a point so if you're wanting the paragraph tag to have a leading of 1 point, it should be altered to be:

X += "<p leading=10> ";
