line up decimals in a table

[Paul]

I am trying to line up 4 variable fields' decimal in a column that is left justified.

I am using text measure to figure out the length of the longest of the 4 fields, subtract the length of each field from the longest length, and make the difference into a tab.

var tb_fld_1 = '<p br="false" findent="'+(lg - tm_fld_1.textWidth)+'">'
table.Rows[1].Cells[1].Content = (tb_fld_1+Field("S_BSC_COVG_AMT"));

Getting closer but not there. Any Ideas of why the measurement is coming up short?
Thanks
