RK-J

In the first table of https://edutestdev-240612.appspot.com/document/pandas-user-guide/u?documentURL=10063%2Frk20oct21%2Fdocs%2Fuser_guide%2Fstyle-Styler-Object-and-HTML-489.html, FE does the following:
- HTML: replace <table id="T_0307f_"> with <table id="T_0307f_" border="1">
- CSS:
--- font-size = 16px (but in the source tables we have 12px)
--- text is centered and numbers are right aligned in source; this is changed and does not look good.
--- gap between text is also changed by our css.

Using class name: rk-table-nb-ra
i.e. nb = no border
& ra = right aligned
