Lines in PowerPoint 2000 tables have arrowheads

Paraphrased from Microsoft technical note Q248236:

CAUSE
Within your presentation, the default Begin style and End style settings for the table lines AutoShape contain arrows.

TO RESOLVE THE PROBLEM

1. Open your PowerPoint presentation.
2. Insert a new blank slide. To do this, click New Slide on the Insert menu.
3. On the Insert menu, click Table.
4. Click OK to accept the default 2-by-2 table.
5. Select the table, and on the Draw menu, click Ungroup. Click Yes when you are asked about converting the table to PowerPoint shapes.
6. Select a line in the table.
7. On the Format menu, click AutoShape.
8. Under Arrows, change the Begin style and End style settings to any non-arrow format.
9. Click to select (place a check mark in) the Default for new objects check box.
10. Click OK.
11. Remove this slide from your presentation.
12. On the File menu, click Save.

Now when you create a new table in your presentation, it will not contain any arrow formatting.

But what if you already have lots of tables with arrows?

Try this bit of VBA fixit code:

Sub DeArrowTables()

    Dim oSl As Slide
    Dim oSh As Shape
    Dim oTbl As Table
    Dim x As Long
    Dim y As Long
    Dim z As Long

    For Each oSl In ActivePresentation.Slides
        For Each oSh In oSl.Shapes
            If oSh.HasTable Then
                Set oTbl = oSh.Table
                With oTbl
                    For x = 1 To .Rows.Count
                        For y = 1 To .Columns.Count
                            For z = 1 To .Cell(x, y).Borders.Count
                                .Cell(x, y).Borders(z).BeginArrowheadStyle = msoArrowheadNone
                                .Cell(x, y).Borders(z).EndArrowheadStyle = msoArrowheadNone
                            Next
                        Next
                    Next
                End With
            End If
        Next
    Next

End Sub
