Cloning line from the table that is inside another table

Hi Sergey,

I have the following function:

Code: Select all

procedure ReplicaLinhasTabela ( Editor : TSRichViewEdit; Data : TStringListArray; ShowProgress : Boolean = False; lblProgress : TLabel = nil ) ;
var
    ItemNo : Integer;

    IndexVar : Integer;
    PossuiVar : Boolean;
    PrimaryIndex : Integer;

    count : Integer;

    j , i , k , b : Integer;
    table : TRVTableItemInfo;

    VariablesEx : string;
    columns : array of TMemoryStream;
begin
    try
        VariablesEx := '';

        for i := Low ( Data ) to High ( Data ) do
        begin
            if Assigned ( Data[ i ] ) = True then
            begin
                for j := 0 to ( Data[ i ] .Count - 1 ) do
                    VariablesEx := iif ( VariablesEx = '' , '{' + Data[ i ] .Names[ j ] + '}' , VariablesEx + ',' + '{' + Data[ i ] .Names[ j ] + '}' ) ;
            end;

How to use:

Code: Select all

ReplicaLinhasTabela ( SRichViewEdit , QueryToArrayList ( memTextoTeste , 'descricao=TITULO_VARIAVEL|variavel=VARIAVEL' ) , False , nil ) ;

But when you have a table inside another table, it replicates wrong. Look (In green it would be correct):


How can I adapt my role?

Thanks!

[Sergey Tkachenko]

Do I understand correctly: the problem is in finding a table for cloning?

But really, how do you define this table?
What if the table contains several nested tables in different cells?

Resolved Sergey!

I adapted the function to access the first table found.

only works up to 2 tables.

Code: Select all

procedure ReplicaLinhasTabelaComTabela ( Editor : TSRichViewEdit; Data : TStringListArray ) ;

    ItemNo : Integer;

    IndexVar : Integer;
    PossuiVar : Boolean;

    count : Integer;

    j , i , k , b , l , m , n , o , p , q : Integer;
    table , table2 : TRVTableItemInfo;

    VariablesEx : string;
    columns : array of TMemoryStream;
begin
    try
        VariablesEx := '';

        for i := Low ( Data ) to High ( Data ) do
        begin
            if Assigned ( Data[ i ] ) = True then
            begin
                for j := 0 to ( Data[ i ] .Count - 1 ) do
                    VariablesEx := iif ( VariablesEx = '' , '{' + Data[ i ] .Names[ j ] + '}' , VariablesEx + ',' + '{' + Data[ i ] .Names[ j ] + '}' ) ;
            end;
        end;

        Editor.Format;

My suggestion: you can give to this table some name, and search for the table with the given name.
For example, you can use item text (the first parameter of AddItem/InsertItem, can be read using GetItemText)
