       Footer w/ hiding: Totals(1), Billed(1), DOS(1), Neg(1), Comm(1), PayAmt(1), Coll(1), PayDate(1), Act(1) = 9 Cells shown
       Need to adjust the final colspan to account for the missing cells.
       Original colspan=3 covered PayDate, Actions + 1 more? Let's assume it should cover the remaining *visible* columns after CollTotal.
       Visible after CollTotal: PayDate(1), Actions(1). Need colspan=1 if we mean the PayDate column.
       Let's simplify and assume the colspan should cover everything after Collected Amount.
       Visible cells: ProviderTotal(1), Billed(1), DOS Spacer(1), Neg(1), Comm(1), PayAmt(1), Red(1), Chk Spacer(1), Coll(1), DateColl Spacer(1), FirmChk Spacer(1), PayDate(1), Action Spacer(1)
       After Hiding (Indices from 1): Billed(2), DOS(3), Neg(4), Comm(5), PayAmt(6), Coll(9), PayDate(12), Actions(13)

       Let's adjust the colspan based on the *updated* number of columns after Commission was added (13 total initially). Hiding 4 leaves 9.
       Structure in HTML: Totals, Billed, Spacer, Neg, Comm, Pay, Red, Spacer, Coll, Spacer*3 = 13.
       Footer cells: 1(Total Label) + 1(Billed) + 1(Spacer) + 1(Neg) + 1(Comm) + 1(Pay) + 1(Red) + 1(Spacer) + 1(Coll) + 3(Colspan) = 12? Let's re-check the PHP.
       PHP tfoot: Totals(1), Billed(1), Spacer(1), Neg(1), Comm(1), Pay(1), Red(1), Spacer(1), Coll(1), colspan="3" (covering DateColl, FirmChk, PayDate, Actions?) -> 1+1+1+1+1+1+1+1+1+3 = 12. Wait, 13 columns in thead.
       thead: Prov, Bill, DOS, Neg, Comm, Pay, ApprRed, ClientChk, CollAmt, CollDate, FirmChk, PayDate, Actions = 13
       tbody: td (Prov), td(Bill), td(DOS), td(Neg), td(Comm), td(Pay), td(ApprRed), td(ClientChk), td(CollAmt), td(CollDate), td(UserChk), td(PayDate), td(Actions) = 13
       tfoot: Totals(1), Billed(1), SpacerDOS(1), Neg(1), Comm(1), Pay(1), Red(1), SpacerChk(1), Coll(1), colspan="3" (Should cover CollDate, FirmChk, PayDate, Actions? - needs colspan 4!)
       Let's assume the initial colspan=3 was wrong and should be 4.
       Now hiding 4 columns (ApprRed(7), ClientChk(8), CollDate(10), FirmChk(11)).
       The corresponding footer cells/spacers: RedTotal(7), SpacerChk(8), SpacerCollDate(10), SpacerFirmChk(11) are hidden.
       Remaining footer: Totals(1), Billed(2), SpacerDOS(3), Neg(4), Comm(5), Pay(6), Coll(9), SpacerPayDate(12?), Actions(13?). Colspan needs adjustment.
       Visible data columns: 1,2,3,4,5,6, 9, 12, 13 (9 columns)
       Visible footer columns: Totals(1), Billed(2), SpacerDOS(3), Neg(4), Comm(5), Pay(6), Coll(9), SpacerPayDate(12), SpacerActions(13)?
