If you talk about value color settings, this can be done by point and click: Right click into the column -> Copy Column Properties. Go to the second table, right click on the column -> Paste Column Properties. Take care that all column properties will be copied and pasted.
In the (i believe) unlikely case of just single cells:
If you have only certain cells colored and want the same cell colored in another table. The only way I know you can do this interactively is
right click, copy column, in new table right click paste column, you will get a new column with just the colored cell, then copy the column entries of interest and paste them into the new column with the colored cell. You may want to delete the old column.
You may want to think about JSL scripting to do this as it will be less error prone.
